Ard Biesheuvel 644e223bb3 Platform/RaspberryPi: create DXE phase SerialPortLib version for RPi3 
The Raspberry Pi 3 derives its 16550 baud clock from the variable core
clock, and so any reprogramming of the baud rate needs to take the
actual core clock value into account.

Introduce a DXE phase version of DualSerialPortLib that discovers this
value in its constructor, using the RPi firmware protocol, and wire it
up for the RPi3 platform.
