ARM: dts: qcom: qcom-msm8226-samsung-ms013g: Add initial device tree

Samsung Galaxy Grand 2 is a phone based on MSM8226. It's similar to the
other Samsung devices based on MSM8226 with only a few minor differences.

The device trees contain initial support with:
 - GPIO keys
 - Regulator haptic
 - SDHCI (internal and external storage)
 - UART (on USB connector via the TI TSU6721 MUIC)
 - Regulators
 - Touchscreen
 - Accelerometer
