arm64: dts: qcom: msm8916-thwc-mf601xx: Add initial device tree

This commit adds support for the MF601 series WiFi/LTE dongle made by
Tong Heng Wei Chuang based on MSM8916.
Compared to previous UFI-001C, MF601 ships more peripherals, such as
battery/charger, SD Card slot, more LEDs and buttons etc.

Note: The original firmware does not support 64-bit OS. It is necessary
to flash 64-bit TZ firmware to boot arm64.

Currently supported:
- All CPU cores
- Buttons
- LEDs
- Modem
- SDHC
- USB Device Mode / Host Mode
- UART
- Charger / Battery
