ArmVirtualizationPkg: add device tree based PL011 SerialPortLib

This adds 2 implementations of SerialPortLib for device tree based platforms
using a PL011 UART:
- an 'early' one which is completely stateless and uses only fixed PCDs
- a normal one which takes its base address from a HOB containing the base
  address discovered in the PEI phase
