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 Signed-off-by: Michał Żygowski <michal.zygowski@3mdeb.com> Change-Id: I35f112e9f9f15f06ddb83b4192f082f9e51a969c Reviewed-on: https://review.coreboot.org/c/coreboot/+/39698 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
