soc/amd/include/msr: factor out P state MSR enable bit to cpu/amd/msr.h
The bit position of the P state enable bit in the 8 P state MSRs is
identical for all AMD chips including the family 16h model 30h APU that
lives outside of soc/amd. The other bits in those 8 MSRs are more or
less family- and model-specific.
