The register HW_SSP_VERSION is broken for ssp version detection,
as the address of the register is different between imx23 and imx28.
Let's use platform_device_id to detect the device, so that the use
of cpu_is_xxx can be removed.

It adds device tree probe for gpio-mxs driver.

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.
