cpu/x86/mp_init: Add code to restart APs

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.

Add API to restart the APs that can be used by Intle TXT driver.

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.
