Add the necessary DSDT files copied from tianocore to boot the RPi4.
In addition generate a board specific SSDT to dynamically enable/disable
ACPI devices based on FDT. This is required to support the various variants
and boot options. It also allows to test the code on QEMU 9.0 without
modifications, since it doesn't emulate PCIe yet.
