A new Arm standard DEN0115A specifies how platforms that don't have
standard ECAM can use the firmware to handle config read/write
operations. This is mostly implemented in TFA but UEFI needs to assure
that there is a description of the root complex in the ACPI namespace.
This set adds that description based on a new menu item which toggles
between XHCI platform description and PCIe via a BDS menu selection on
the RPi4. The CM4 is really the platform that needs this as it has a
PCIe slot. On that platform PCIe is enabled by default.
v2->v3:
Remove ACPI0004 container around PCI root bridge along with some
whitespace/tweaks to the Pci.asl file.
Add Linux quirk _DSD patch at the end.
v1->v2:
Use global shared interrupts in PCI PRT which is a pretty
significant simplification.
Modify bus max to use the secondary side of the root port for
enforcing device limits
Various other AML cleanups per Ard (drop redundant _DMA, bump UID
to make it unique, etc)
Break link status move into its own patch
MADT->MCFG typos in various comments
Commit message tweaking
