soc/intel/alderlake: 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:350623902
TEST=reboot test on 40 google/xol by ODM, all passed w/o
hang.
