ArmVirtPkg/FdtPL011SerialPortLib: Set the PL011 UART clock rate
The interface to PL011UartInitializePort has changed in
ArmPlatformPkg/Drivers/PL011Uart with the title:
"ArmPlatformPkg: Add support to configure PL011 UART clock"
This patch updates the calls to PL011UartInitializePort(), in line with
that change, adding a parameter value using the PCD previously used
directly by the driver.
