Add device tree for Motorola Moto G2 (2014) (motorola-titan) smartphone
based on the Qualcomm MSM8226 SoC.
Initially supported features:
- Buttons (Volume Down/Up, Power)
- eMMC
- Hall Effect Sensor
- Simple framebuffer display
- Vibrator
Based on device tree for similar device msm8226-motorola-falcon.
Initial commit for falcon notes that dhob and shob reserved-memory
regions seem to be related to a Motorola specific mechanism. [1]
