Platforms/ARM: add PcdUartDefaultReceiveFifoDepth
The upstream code uses a PCD to set the FIFO depth:
f423d76 2016-03-17 MdeModulePkg/SerialDxe: Set FIFO depth with PCD
Add a sensible default for the PCD before the code becomes more widely
used.
The PL011UartInitializePort function in the PL011 driver expects the
receive FIFO depth to be set to a sane value or zero to use the
appropriate default for the version of PL011 present on the device.
