Add a device tree for the Motorola Moto G (2013) smartphone based
on the Qualcomm MSM8226 SoC.
Initially supported features:
- Buttons (Volume Down/Up, Power)
- eMMC
- Hall Effect Sensor
- SimpleFB display
- TMP108 temperature sensor
- Vibrator
Note: the dhob and shob reserved-memory regions are seemingly a part of some
Motorola specific (firmware?) mechanism, see [1].

Changes in V2:
- split hob-ram reserved-memory region into dhob and shob
- add a note and a link to downstream documentation with more
information about these regions
