amd/stoneyridge: Change ACPI _PR.CPxx to _PR.Pxxx
This is a bug introduced by this commit: stoneyridge: Fix CPU ASL \_PR table [commit I870f81] The following error is found in dmesg ACPI Error: [\_PR_.P000] Namespace lookup failure, AE_NOT_FOUND... ACPI Exception: AE_NOT_FOUND, During name lookup/catalog... ACPI Exception: AE_NOT_FOUND, (SSDT:AGESA ) while loading table... ACPI Error: 1 table load failures, 3 successful... ... acpi-cpufreq: overriding BIOS provided _PSD data And, "ls -la /sys/devices/system/cpu/cpufreq/" doesn't work The cause is that the Pstate SSDT table generated by AGESA expects CPU variables \_PR.Pxxx, not \_PR.CPxx as generated by coreboot. Use Kconfig to set the required string.
