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