Eric Bénard 9a4cc05653 ARM: mxs: Add support for the eukrea-cpuimx28. 
The following devices/functionalities were tested:
 * Main UART.
 * Ethernet0.
 * Ethernet1.
 * SD.
 * USB host.
 * USB otg.
 * Display(and its backlight).
 * Touchscreen.
 * Audio.
 * nand.
 * i2c and the pcf8563 device.
 * The gpio buttons.
 * The gpio leds.
 * Watchdog
