This(2nd) file is generally imported from ACPICA directly.

So you need to work with acpica-devel list(you can cc Robert Moore) to
get that alone integrated in acpica projected so that iasl tool and
other related components also gain support for this first.

If the ACPI tables are generated by UEFI, it would be good to add the
support in tianocore project. IIRC tianocore has some PCC reference in
Acpi60.h header.

It would help if the above two are done before we start looking into
Linux changes(pcc.c). To summarize this patch needs to be split.
