The generic dpi panel driver now sets the gpios required to configure the panel.
This was previously done in platform_enable/disable callbacks in board files.
All the board files using generic dpi panel now correctly pass the gpio related
information as platform data, which is needed by the panel driver to configure
the panel. Hence, the platform_enable/disable ops can be safely removed now.

The generic dpi panel driver leaves gpio configurations to the platform_enable
and disable calls in the platform's board file. These should happen in the
panel driver itself.
Add a generic way of passing gpio information to the generic dpi panel driver
via it's platform_data. This information includes the number of gpios used by
the panel, the gpio number and logic level (active high/low) for each gpio. This
gpio data will be used by the driver to request and configure the gpios required
by the panel.
This will help in removing the need for the panel drivers to have platform
related callbacks.

Use devm_kzalloc instead of kzalloc to allocate driver data for the generic dpi

Structs for platform data of omapdss panels are found in headers in the
'include/video/' path. Board files populate these structs with platform
specific values, and the panel driver uses these to configure the panel.
Currently, each panel has it's own header in the above path. Move all the
omapdss panel platform data structs to a single header omap-panel-data.h.
This is useful because:
- All other omapdss panel drivers will be modified to use platform data. This
would lead to a lot of panel headers usable only by omapdss. A lot of these
platform data structs are trivial, and don't really need a separate header.
- Platform data would be eventually removed, and platform information would be
passed via device tree. Therefore, omapdss panel platform data structs are
temporary, and will be easier to remove if they are all in the same header.
- All board files will have to include the same header to configure a panel's
platform data, that makes the board files more consistent.

The panel drivers contain enable, disable, suspend and resume calls.
The suspend and resume are effectively identical to disable and enable.
This patch removes panel suspend and enable code from omapdss and the
panel drivers, and replaces their use with enable and disable.

The DPI driver currently relies on the omap_dss_device struct to configure the
number of data lines as specified by the panel. This makes the DPI interface
driver dependent on the omap_dss_device struct.
Make the DPI driver data maintain it's own data lines field. A panel driver
is expected to call omapdss_dpi_set_data_lines() before enabling the interface.

The timings maintained in omap_dss_device(dssdev->panel.timings) should be
maintained by the panel driver itself. It's the panel drivers responsibility
to update it if a new set of timings is to be configured. The DPI interface
driver shouldn't be responsible of updating the panel timings, it's responsible
of maintianing it's own copy of timings.

The DPI driver currently relies on the timings in omap_dss_device struct to
configure the DISPC accordingly. This makes the DPI interface driver dependent
on the omap_dss_device struct.
Make the DPI driver data maintain it's own timings field. The panel driver is
expected to call dpi_set_timings()(renamed to omapdss_dpi_set_timings) to set
these timings before the panel is enabled.
In the set_timings() op, we still ensure that the omap_dss_device timings
(dssdev->panel.timings) are configured. This will later be configured only by
the DPI panel drivers.

The generic DPI panel driver doesn't currently have locking to ensure that
the display states and the driver data is maintained correctly. Add mutex
locking to take care of this. Add a new get_timings driver op to override the
default get_timings op. The new driver op contains locking to ensure the correct
panel timings are seen when a DSS2 user calls device->driver->get_timings.

omap_panel_config contains fields which are finally written to DISPC_POL_FREQo
registers. These are now held by omap_video_timings and are set when the manager
timings are applied.
Remove the omap_panel_config enum, and remove all it's references from panel or
interface drivers.

Some panel timing related fields are contained in omap_panel_config in the form
of flags. The fields are:
- Hsync logic level
- Vsync logic level
- Data driven on rising/falling edge of pixel clock
- Output enable/Data enable logic level
- HSYNC/VSYNC driven on rising/falling edge of pixel clock
Out of these parameters, Hsync and Vsync logic levels are a part of the timings
in the Xorg modeline configuration. So it makes sense to move the to
omap_video_timings. The rest aren't a part of modeline, but it still makes
sense to move these since they are related to panel timings.
These fields stored in omap_panel_config in dssdev are configured for LCD
panels, and the corresponding LCD managers in the DISPC_POL_FREQo registers.
Add the above fields in omap_video_timings. Represent their state via new enums.
Add these parameters to the omap_video_timings instances in the panel drivers.
Keep the corresponding IVS, IHS, IPC, IEO, RF and ONOFF flags in
omap_panel_config for now. The struct will be removed later.

Remove configuration of Ac-bias pins
Ac-bias pins need to be configured only for passive matrix displays. Remove
acbi and acb fields in omap_dss_device and their configuration in panel
drivers. Don't program these fields in DISP_POL_FREQo register any more.
The panel driver for sharp-ls037v7dw01, and the panel config for
Innolux AT070TN8 in generic dpi panel driver set acb to a non zero value. This
is most likely carried over from the old omapfb driver which supported passive
matrix displays.

Generic DPI panel driver includes the driver and 4 similar panel configurations. It
will match the panel name which is passed from platform data and setup the
right configurations.
With generic DPI panel driver, we can remove those 4 duplicated panel display
drivers. In the future, it is simple for us just add new panel configuration
date in panel-generic-dpi.c to support new display panel.
