ACPI: Add function to write _PPC using NVS
The existing NVS variable for PPCM will be used to
select a dynamic max P-state.
By itself this does not change existing behavior because
the NVS PPCM variable is initialized to zero.
PPCM can be tested by building and booting a modified BIOS
that sets gnvs->ppcm to a value greater than 1 and checking
from the OS that the P-state is limited to that value.
