Revert "TerminalDxe: select the UART's default receive FIFO depth" 

This reverts commit 31ae446b1a.
Changing the receive FIFO depth in Terminal driver Start() is not
recommended.
A new PCD PcdUartDefaultReceiveFifoDepth was added and
MdeModulePkg/SerialDxe driver uses the PCD as the default receive
FIFO depth.
