soc/intel/xeon_sp: Set IA32_SMRR_PHYSMASK lock bit
smm_relocation_handler is run for each thread but IA32_SMRR_PHYS_BASE and IA32_SMRR_PHYS_MASK are core scope, need to avoid writing the same MSR that has been locked by another thread. Tested=On OCP Crater Lake, rdmsr -a 0x1f3 can see all cores set the lock bit.
