arm64: dts: qcom: msm8939-samsung-a7: Add initial dts

This dts adds support for Samsung Galaxy A7 smartphone released in 2015.

Add a device tree for A7 with initial support for:

- GPIO keys
- Hall Sensor
- SDHCI (internal and external storage)
- USB Device Mode
- UART (on USB connector via the SM5502 MUIC)
- WCNSS (WiFi/BT)
- Regulators
- Touch key
- Accelerometer/Magnetometer
- Fuelgauge
- NFC
- Vibrator
- Touchscreen
