On some platforms the UART clock is not the same for all the serial
ports. The PL011 driver must be capable of handling serial ports with
different clock rates, so must not rely on a PCD for the clock rate.
This patch allows the UART clock rate to be passed as a parameter
to PL011UartInitializePort(), which is called from the serial port
library. This patch also contains the corresponding changes in the
serial port library.
The PCD in Drivers/PL011Uart is replaced by an extra parameter for
PL011UartInitializePort. The PCD is moved to Library/PL011SerialPortLib
to supply the value to pass.
A corresponding patch to ArmVirtPkg is included in the same bundle to
align that with these changes.

The PCDs used in the PL011 UART Driver and Serial Port Library are
inherently "fixed at build". This change updates the source to use
Fixed PCDs for these values. This improves clarity and efficiency.

EmbeddedPkg/SerialDxe was not allowing to set/get the control of the
Serial connection because the needed functions were not exposed in
SerialPortLib.h.
This commit introduces an additional library to extend the SerialPort
features.

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.
