soc/amd/phoenix: introduce and use pstate_msr bitfield struct
Add the pstate_msr union of a bitfield struct and a raw uint64_t to
allow easier access of the bitfields of the P state MSRs and use this
bitfield struct in get_pstate_core_freq and get_pstate_core_power. The
signature of those two function will be changed in a follow-up commit.
PPR #57019 Rev 1.65 and PPR #57396 Rev 1.54 were used as a reference as
well as the reference code. This patch also adds and uses the cpu_vid_8
bit which is the 9th bit of the voltage ID specified in the SVI3 spec.
