In preparation for adding Raspberry Pi 4 support, the Pi 3 platform is restructured by factorizing all the drivers and libraries that are going to be commonly used by the two platforms. Because much of the Pi 4 SoC is an extension of the Pi 3 one this means that almost everything, except the ACPI tables, is moved up into a new common RaspberryPi/ subdirectory that will serve both platforms. The .dec is also moved to this directory, under a new RaspberryPi.dec name, and existing references to it are updated. This commit requires the edk2-non-osi in use to contain commit 243e55f622ea in order to build.
