Michael Niewöhner cbd4ee73d7 cpu/intel/common: correct MSR for the Nominal Performance in CPPC
The "Nominal Performance" is not the same as the "Guaranteed
Performance", but is defined as the performance a processor can deliver
continously under ideal environmental conditions.

According to edk2, this is the "Maximum Non-Turbo Ratio", which needs to
be read from MSR_PLATFORM_INFO instead of IA32_HWP_CAPABILITIES.

Correct the entry in the CPPC package.

Test: dumped SSDT from Supermicro X11SSM-F and checked decompiled
version
