[PATCH 4/8] ARM: imx: add support code for IMX50 based machines

[gerg at uclinux.org]

From: Greg Ungerer <gerg at uclinux.org>

Add machine support code for the Freescale IMX50 SoC.

It is very similar to the Freescale IMX53, it contains many of the same
periperhal hardware modules, at the same address offsets as the IMX53.
(Notable exceptions are that the IMX50 contains no CAN bus hardware, less
GPIO, no VPU, it does contain an Electrophoretic display controller though).

So this support code just uses the IMX53 definitions as they are today.
We can add the extra IMX50 definitions in the future when required.
