soc/intel/meteorlake: Fix system hang by enabling SMI handling

Browse source 
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.
