The two SoCs have different PHYS_OFFSETs so it's not (yet) possible to
compile a single (working) kernel for these.

The symbols in this choice should only be used to select between the
available machines that can be built into a single kernel. As these sets
(will) differ e.g. depending on ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR
letting them select other symbols makes the logic more complex and needs
to duplicate some things. So let the machines select the corresponding
symbols (indirectly via SOC_XYZ).

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

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)

Current code inside babbage_usbhub_reset uses gpio_direction_output with initial value of the GPIO and also sets
the GPIO value via gpio_set_value to the same level right after. This is not needed.
By using gpio_request_one it is possible to set the direction and initial value in one shot.
