soc/intel/meteorlake: Fix system hang by enabling SMI handling
Issue: System hang occurred due to unhandled SPI synchronous SMI, triggered by LOCK_ENABLE bit and WPD assertion.
Solution: Enabled SOC_INTEL_COMMON_BLOCK_SMM_TCO_ENABLE configuration to allow the system to handle and clear SPI synchronous SMI.
BUG=b:306267652 TEST=Cold reboot test on 20 google/screebo by ODM, all passed w/o hang.
