b78d8e59a6 gpio/mxc: Change gpio-mxc into an upstanding gpio driver
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.

f4bf03d8b7 ARM: imx: remove #includes already available from devices-common.h
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)

3dac219615 ARM: imx: use .init_early to initialize cpu type and reset address
This used to be done in .map_io which is supposed to only setup the
memory mapping.

6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

6c80ee5170 ARM: imx: make all pin lists const and signed, move to .init where possible
Making the lists signed fixes sparse warnings like:

	arch/arm/mach-imx/mach-mx27_3ds.c:94:31: warning: incorrect type in argument 1 (different signedness)
	arch/arm/mach-imx/mach-mx27_3ds.c:94:31:    expected int const *pin_list
	arch/arm/mach-imx/mach-mx27_3ds.c:94:31:    got unsigned int static [toplevel] *<noident>
