This is preparation work for the introduction of clockevent frequency
update with a clock notifier. This is only possible when the device
is passed a clk struct, so let's split the legacy and devicetree
initialization.

This commit adds the required checks on the functions that return
an error. Some of them are not critical, so only a warning is

For the clock to be used (e.g. get its rate through clk_get_rate)
it should be prepared and enabled first.
Also, while the clock is enabled the driver must hold a reference to it,
so let's remove the call to clk_put.

Commit 6dd747825b20 ("ARM: imx: move timer resources into a structure")
moved initialization parameters into a data structure, but neglected to set
the irq field in that data structure for non-DT boots. This causes the system
to hang if a non-DT boot is attempted.

Migrate timer-sp driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.
There are few more changes worth noticing:
- The clockevent device was disabled by writing: 'TIMER_CTRL_32BIT |
TIMER_CTRL_IE' to ctrl register earlier. i.e. by un-setting the
TIMER_CTRL_ENABLE bit. Its done by writing zero now and should have
the same effect.
- For shutdown and resume we were writing the same value twice to the
register (to disable the timer), which is fixed now.
- Switching to oneshot mode was divided into two parts earlier:
- Firstly set_mode() was writing:
'TIMER_CTRL_32BIT | TIMER_CTRL_IE | TIMER_CTRL_ONESHOT'
to ctrl register (device not enabled yet)
- Then sp804_set_next_event() was enabling the device by writing
'readl(ctrl) | TIMER_CTRL_ENABLE' to the ctrl register. This was
unnecessarily complicated.
- Change this to: Stop device on set_state_oneshot and configure it in
sp804_set_next_event().

Migrate timer-imx-gpt driver to the new 'set-state' interface provided
by clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.
Also drop:
- 'imx_timer.cem': It was caching the last state of the clockevent
device. The same behavior can be achieved by using clockevents state
helpers. These helpers are only required for oneshot mode as
shutdown/resume wouldn't be done twice by the core.
- 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore
by drivers. The prints are modified to print the set-state functions
name now to debug the driver.

Since the removal of the r8a7740 legacy SoC code in commit
44d88c754e57a6d9 ("ARM: shmobile: Remove legacy SoC code for R-Mobile
A1"), all former users of the "sh-cmt-48-gen2" platform device name are
only supported in generic DT-only ARM multi-platform builds. The driver
doesn't need to match platform devices by name anymore, hence remove the
corresponding platform_device_id entry.

Commit d2348fb6fdc6 ("tick: Dynamically set broadcast irq affinity")
adds one excellent feature CLOCK_EVT_FEAT_DYNIRQ to let the core set the
interrupt affinity of the broadcast interrupt to the cpu which has the
earliest expiry time. This patch adds CLOCK_EVT_FEAT_DYNIRQ flag to
avoid unnecessary wakeups and IPIs when the dw_apb_timer is used as
broadcast timer.
A simple test:
~ # rm /tmp/test.sh
~ # cat > /tmp/test.sh
cat /proc/interrupts
for i in `seq 10` ; do sleep $i; done
cat /proc/interrupts
~ # chmod +x /tmp/test.sh
~ # taskset 0x2 /tmp/test.sh

same state twice and so perhaps the check wasn't required.
- 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore
by drivers and it was used just to print old-state:new-state. The
debug prints are called from mxs_irq_clear() now based on the
state-name passed to it. The printed name will be same for shutdown
and resume states as they use the same callback pointer.
