soc/amd/*/include/msr: drop _LO part from PSTATE definition names

The _LO part in the definition names is a leftover from before moving to
the pstate_msr union access to the bitfield elements where it still
mattered if a bit was in the lower of higher half of the MSR. With the
mask-and-shift access to the two parts of the MSR being gone, the _LO
part in the name isn't useful any more and possibly a bit misleading, so
drop that part.
