It removes the use of cpu_is_xxx from gpio-mxs driver and instead use platform_device_id to identify the device. Accordingly, mxs platform code is changed to register gpio device with different names, and the registeration are done in soc specific initialization functions now, so postcore_initcall(mxs_add_mxs_gpio) gets removed.
