Changes:
1. Add code to ConfigDxe driver and AcpiTables module to dynamically
build either Mini UART or PL011 UART info in ACPI. This also fixes
the issue discussed in https://github.com/pftf/RPi4/issues/118.
2. Cleanup by moving duplicate Debug Port 2 table related defines and
structures to a newly created header file (RpiDebugPort2Table.h).
Testing Done:
- Booted to UEFI shell and use acpiview command to check the result of
the different UART settings in config.txt (enabling either Mini UART
or PL011) and SPCR, DBG2 tables and device BTH0 are dynamically
changed as expected.

Lets sync our mailbox commands with the known/Linux
constants so that we have a more complete view of
what we can request from the VPU.

Newer Pi 4 boards (such as 8GiB variant) no longer carry a SPI
EEPROM with the VLI805 (USB) controller firmware. So, ask the
VPU firmare to load the image it has into the controller
specified by BDF.
This is benign on non-8GiB boards (reloading that firmware if
VPU fw is new enough or doing nothing on old VPU firmware).
Tested on 4GB. Also have a positive test report for an 8GB board
from a forum member.

Besides the base memory size, we can read the GPU/VideoCore base as
well as the model during early init, which we'll need for improving
the memory mapping.
This patch adds the retrieval of these variables, as well as some
early debug display of their values (which can be useful) and also
removes unused variables such as mGPUMemoryBase and mGPUMemoryLength.

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.
