Irene Park c8edb70945 ArmPlatformPkg/PL011UartLib: Check PID2 if FiFoDepth is zero
PL011UartLib determines its FIFO depth based on the PID2 value but
the register PID2 is not mandatory as per the SBSA spec.
This change won't check PID2 if PcdUartDefaultReceiveFifoDepth is set
to a value > 0.

Ard Biesheuvel 12156134fe ArmPlatformPkg: reorganize PL011 code
The PL011 code in ArmPlatformPkg is organized in a weird way: there is
a single PL011Uart.h header file under Include/Drivers containing both
register definitions and function entry points. The PL011Uart library
itself is in Drivers/ but it is actually a library.

So let's clean this up: add a new PL011UartLib library class and associated
header file containing only the library prototypes, and move the library
itself under Library/ using a new GUID, with the register definitions moved
into a local header file.
