Leverage the Pstate table created by AGESA.
The name of processor created by AGESA is P00n, whose P is BLDCFG_PROCESSOR_SCOPE_NAME(is 'C' if it is undefined.) and n starts from 0. The dsdt should be aligned with that. This feature has only been tested on persimmon. The changes on all the other boards were propagated.
