There is no need for using a MX51-specific version of imx_add_gpio_keys.

Remove imx51_add_gpio_keys and use imx_add_gpio_keys instead.

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)

The boards are currently using otg_ulpi_create and mxc_ulpi_access_ops,
both are only present if CONFIG_USB_ULPI is set. To remove the need of
ifdefs in the board code introduce a imx_otg_ulpi_create functions
which expands to a static inline function if compiled without ulpi.
