pl011 releases earlier than r1p5 has a fifo depth of 16 bytes, whereas
version r1p5 upwards has a fifo depth of 32 bytes. The pl011 driver was
hardwired to 32 byte depth, causing dropped characters on some platforms
(including default settings on FVP Base and Foundation models).
Update driver to select 16 or 32 on port initialization by checking the
component revision.

Because this driver can be used for different purposes (Terminal, Debug port, communication),
its initialization function has been extended to accept additional settings.

This library makes the interface with the PL011 UART controller.
This library can be linked to different types of driver (Serial Console,
debugger, etc) using PL011 UART controller.
ArmPlatformPkg/PL011SerialPortLib: Use Drivers/PL011Uart
Remove the direct accesses to the PL011 UART controller to use the PL011Uart
library.
