soc/intel/xeon_sp: select SCO_INTEL_COMMON_BLOCK_TCO
Also disable TCO timer through calling tco_configure().
If tco_configure() is not called, the TCO timeout would
trigger SMI periodically about every 2 seconds with SMM log:
"TCO_STS: BIT18 TIMEOUT"
Tested=On AC CRB, does not see periodic SMI log.
