The patch removes imx_idle hook and use pm_idle instead to get imx
arch_idle prepared for the cleanup. It's suggested by Russel King
as below.
> The final removal of mach/system.h depends on getting rid of the arch_idle
> thing. While going through these headers, I was dismayed to find these:
>
> arch/arm/mach-s3c2410/include/mach/system.h:void (*s3c24xx_idle)(void);
> arch/arm/plat-mxc/include/mach/system.h:extern void (*imx_idle)(void);
>
> when we have a perfectly good pm_idle hook already in place - so there's
> no excuse for these especially when other platforms are already using
> pm_idle to hook their platform specific idle function into. This is
> something that better be gone at the next merge window!

This patch adds an idle hook imx_idle to be called in arch_idle().
Any soc that needs a customized idle implementation other than
cpu_do_idle() can set up this hook in soc specific call.

Currently each i.MX processor has its own function for displaying the silicon
revision.
Introduce a generic function for this purpose, so that all i.MX processors can
reuse it.

The patch removes all the uses of cpu_is_mx(). Instead, it utilizes
platform_device_id to distinguish the different gpio types, IMX1_GPIO
on i.mx1, IMX21_GPIO on i.mx21 and i.mx27, IMX31_GPIO on all other
i.mx SoCs.

The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.
* Add a list to save all mx2 ports references, so that
mx2_gpio_irq_handler can walk through all interrupt status
registers
* Use readl/writel to replace mach-specific accessors
__raw_readl/__raw_writel
* Change mxc_gpio_init into mxc_gpio_probe function
* Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
be public at all, and also make some other cleanup on
plat-mxc/include/mach/gpio.h at the same time
And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

Since support for mxc91231 was introduced 2009 it only saw patches that
were part of (mxc or arm) global cleanups. The only supported machine
only had 4 devices (2x UART, sdhc, watchdog).

Having the silicon revision to appear on the boot log is a useful information.
MX31, MX35 and MX51 already show the silicon revision on boot.
Add support for displaying such information for MX53 as well.
Tested on a mx53loco board, where it shows:
CPU identified as i.MX53, silicon rev 2.0

This patch adds clock support for i.MX35 SoCs. We do not support setting
of clock rates yet, but most interesting clock rates should be reported.
I couldn't test all clock rates and the datasheet contains some obvious
bugs, so expect some bugs in this code.

We had hardcoded cpu_is_ macros for mxc architectures till now. As we
want to run the same kernel on i.MX31 and i.MX35 this patch adds cpu_is_
macros which expand to 0 or 1 if only one architecture is compiled in and
only check for the cpu type if more than one architecture is compiled
in.
