[PATCHv4] ARM: dts: Add support for the cpuimx53 board from Eukrea and its baseboard.

[Denis Carikli]

The following devices/functionalities were added:
 * Main and secondary UARTs.
 * i2c and the pcf8563 device.
 * Ethernet.
 * NAND.
 * The BP1 button.
 * The LED.
 * Watchdog.
 * SD.
 * USB host.
 * USB otg(device and host).

ChangeLog v3->v4:
- Reordered the Cc list and dropped the Cc to the devicetree binding maintainers.
- Added USB otg support.
- Cosmetic cleanups in the iomuxc node, the esdhc1 node was updated accordingly.

ChangeLog v2->v3:
- Removed the useless regulator-always-on
- Added the rts and cts pins to the uart1 pinctrl

ChangeLog v1->v2:
- Added the board target in arch/arm/boot/dts/Makefile
- Fixed the gpios to now use the gpios defines.
- Fixed the button linux code to now use an input define.
- Fixed the regulator.
