ARM: dts: qcom: Add support for Motorola Moto G (2013)

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].
