[PATCH] efikamx: reintroduce Genesi Efika MX Smarttop via device tree

This device tree only supports the final retail board ("TO3").
It is currently feature equivalent to the MX51 Babbage device tree. The
following features have been tested and work as well as can be expected:
* Serial port
* SD card support
* I2C bus
* SGTL5000 audio support via the internal speaker
* SDMA support (via audio)
* SPI bus
* NOR flash (at 25MHz bus speed)
* MC13892 PMIC Regulator and Realtime clock functions
Since the board requires some extra work on the PMIC to power off, the system
will instead just halt, however reboot works. Other missing features are due
to a lack of drivers or device tree bindings currently.
