[PATCH edk2-platforms v3 7/8] Platform/RaspberryPi4: Remove PlatformPcdLib

["Ard Biesheuvel" <ard.biesheuvel@arm.com>]

From: Andrei Warkentin <awarkentin@vmware.com>

Remove the PlatformPcdLib. It is completely unnecessary. Originally,
this was meant for the GENET driver, but now that ConfigDxe registers
the platform device, the library is superfluous.
