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

ChangeLog v10->v13:
- The display part was splitted out because it depends on other
  patches that are not applied yet, the commit message was updated accordingly.
- The new GPIO and input defines are now used in the dts(i).

ChangeLog v9->v10:
- Adapted to the new pingrp patches.

ChangeLog v8->v9:
- Licenses were shortened.
