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.
