soc/intel/common: Use SPR for backing up data way and eviction mask
This patch replaces the usage of GPR (General Purpose Registers) like ECX and EBX for backing up data way and non-eviction mask with SPR (Special Purpose Registers) EDI and ESI. Purpose of this change is to ensure the safety while developers might use ECX often while doing rdmsr/wrmsr rather than making use of EDI. TEST=Able to boot JSL and TGL platform without any hang using eNEM.
