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-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.
BRANCH=none
BUG=b:64885241
TEST= Check dmeg and ls -la /sys/devices/system/cpu/cpufreq/
