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.

This used to be done in .map_io which is supposed to only setup the
