security/intel/stm: Check for processor STM support
Check to ensure that dual monitor mode is supported on the
current processor. Dual monitor mode is normally supported on
any Intel x86 processor that has VTx support. The STM is
a hypervisor that executes in SMM dual monitor mode. This
check should fail only in the rare case were dual monitor mode
is disabled. If the check fails, then the STM will not
be initialized by coreboot.
