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.
