The Raspberry Pi 4 Broadcom Genet network adapter can be made to work in ACPI
mode under high level OSes such as Linux.

To facilitate this however, it is desirable to ensure that the platform's MAC
address has properly been written to the dedicated UMAC registers during UEFI
initialization.

This series of patches achieves that by:
* Adding a generic Genet driver stub under Silicon that, for the time being,
  simply performs UMAC init when a MAC Address PCD has been set.
* Adding a new PlatformPcdLib in the Raspberry Pi try, to ensure that, if
  no MAC address PCD was provided for the build, we set that PCD by querying
  the firmware interface.
* Enabling the Genet driver for the Pi 4 platform
