arm64: dts: qcom: msm8916-lenovo-phab: add device

Lenovo PHAB (PB1-750M) is a phablet using the
MSM8916 SoC released in late 2015.

Add a device tree for with initial support for:

- GPIO keys
- pm8916-vibrator
- SDHCI (internal and external storage)
- USB Device Mode
- Charging
- UART (not tested)
- WCNSS (WiFi/BT)
- Modem (LTE works, calls & SMS not tested)
- Regulators
- Sound (WIP)
- Accelerometer (WIP)
