arm64: dts: qcom: msm8916-yiming-uz801v3: Add initial device tree

This commit adds support for the uz801 v3.0 WiFi/LTE dongle made by
Henan Yiming Technology Co., Ltd. based on MSM8916.

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
- UART
