[PATCH 1/2] hyper-v: check frequency MSRs presence according to the specification

Hyper-V TLFS specifies two bits which should be checked before accessing frequency MSRs: - AccessFrequencyMsrs (BIT(11) in EAX) which indicates if we have access to frequency MSRs. - FrequencyMsrsAvailable (BIT(8) in EDX) which indicates is these MSRs are present. Rename and specify these bits
