[WIP] soc/amd/picasso/mca: fix CTL_MASK access

MC0_CTL_MASK is no longer available in fam 17h and newer and will result
in a general protection fault when accessed. This register was moved to
the MCAX banks, so use that.

TODO: add proper defines and don't use a magic MSR register index

BUG=b:186038401
