acpi: correct the processor devices scope
The ACPI Spec 2.0 states, that Processor declarations should be made
within the ACPI namespace \_SB and not \_PR anymore. \_PR is deprecated
and is removed here.
Additionally add processor scope patching for P-State SSDT created by
AGESA, becasue AGESA creates the tables with processors in \_PR scope.
TEST=boot Debian Linux on PC Engines apu2, check dmesg that there are
no errors, decompile ACPI tables with acpica to check whether the
processor scope is correct and if IASL does not complain on wrong
checksum, run FWTS
