security/intel/txt: Restart APs after successful SCHECK
When INTEL_TXT is enabled, the APs are stopped before a SCHECK call to ACM is invoked. However, SCHECK happens before the final MTRRs are programmed on APs. This results in MTRR programming failure on APs on platforms using INTEL_TXT.
Restart the APs after SCHECK attempt to ensure the APs have their MTRRs programmed correctly.
TEST=Run coreboot with INTEL_TXT enabled on Protectli VP4670 and see coreboot no longer complains on inability to run a MTRR programming task on APs.
