ARM: dts: qcom: msm8226: Support Motorola Moto G2 (2014)

Browse Source 
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]
