Add various functionality needed to enable a imx53 low power idle
state.  This includes adding the imx53 gpc_dvfs clock and making a
common imx5_late_init function and initializing all imx53
 MACHINE_STATE late_init calls to imx5_late_init.

This patch moves the contents of arch/arm/mach-mx5 to arch/arm/mach-imx
and adjusts the Makefile/Kconfig entries in a way that it's possible
to compile i.MX5 together with i.MX3/6.

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.

Most machine files include "devices-imxXX.h" which in turn includes
<mach/devices-common.h>.  The latter already includes many headers
that the machine files don't need to include again.

These were found by:

 $ grep \#include arch/arm/plat-mxc/include/mach/devices-common.h > tmpfile
 $ git grep -l 'devices-imx' arch/arm | xargs grep -f tmpfile -F

(but I kept linux/init.h, linux/kernel.h and linux/platform_device.h)

As there is a mx53_smd board in the kernel, using SMD_FEC_PHY_RST as the pin name can be misleading when used
on a MX53_EVK board.

Change the pin name to reflect the board name.

Current code inside mx53_evk_fec_reset uses gpio_direction_output with initial value of the GPIO and also sets
the GPIO value via gpio_set_value right after. This is not needed.

By using gpio_request_one it is possible to set the direction and initial value in one shot.
