soc/intel/mtl: Adaptively disable 3-strike error for QS silicon
This patch provides a way to mask the 3-strike error on Intel
Meteor Lake SoC platform across pre-prod and prod SoC.
This patch decouples MSR selection for 3-strike error disablement, ensuring compatibility across SoC types.
Without the correct MSR been programmed the SoC platform is unable to disable 3-strike error.
BUG=b:314883362
TEST=Disable the 3-strike on google/screebo with QS silicon.
