[Nico Huber (Code Review)]

Hello Werner Zeh, Aaron Durbin, Patrick Rudolph, Subrata Banik, build bot (Jenkins),

I'd like you to reexamine a change. Please visit

soc/intel/apl: Call mca_configure() on cold boots only

By APL BIOS Spec, we must not do this on warm boots. Also, an
x5-E3940 hangs in tests after touching these MSRs on a warm boot.

The TODO comment seems stale and copied over. So the actual
requirements for SGX are unknown and we add a guard for that
case.

TEST=Confirmed that warm boots on Kontron/mAL10 don't hang any more.
