PS11, Line 54: * enumeration.
How do we handle the mapping to the ACPI device names?
Looks like we map the final BDF to RP01..16 (don't ask me why 16, I don't know
any chip supported by this code that has exactly 16 ports). However looking through
the ASL code, I found a gimmick: it reads the port number from LCAP. AIUI, that
should give us the original function number (off by one). I'll investigate further.
