Add initial support for Xiaomi Mi 9 smartphone, based on
Qualcomm SM8150 (Snapdragon 855) chipset.
Currently the following features are supported:
* reserved-memory map
* debug UART
* display using simple-framebuffer
* physical keys: power, volume up/down, AI key
* reboot modes
* regulator voltages
* USB peripheral mode
