As ACPI tables are little endian this is the reverse of the ordering used by PCI_BUILD_BDF(). As a minimal fix split the QEMU BDF up into bus and devfn and write them as single bytes in the correct order.

If the ACPI handle form is needed then that can be introduced alongside this with little duplicated code. Drop the PCIDeviceHandle in favor of just passing the bus, devfn and segment directly. devfn kept as a single byte because ARI means that in this case it is just an 8 bit function number.

Here we add these ports such that they may be targets of hmat_lb records to describe the latency and bandwidth from host side initiators to the port. A discoverable mechanism such as UEFI CDAT read from CXL devices and switches is used to discover the remainder of the path, and the OS can build up full latency and bandwidth numbers as need for work and data placement decisions.
