Merge changes in edk2-platforms-raspberrypi-pl011-bth-noflow.diff in
https://github.com/worproject/RPi-Bluetooth-Testing/ for enabling
Bluetooth and serial port (Mini UART) in Windows OS.
Testing Done:
- Successfully booted Windows 10 (20279.1) on SD (made by WOR) with
the RPi-Windows-Drivers release ver 0.5 downloaded from
https://github.com/worproject/RPi-Windows-Drivers/releases
and checked that both Bluetooth and serial port (Mini UART) can
work fine.
