soc/amd/picasso: 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.

TEST=The coreboot-generated SSDT containing the P state packages stays
identical on Mandolin.
