soc/intel/apollolake: Drop privilege level to IA_UNTRUSTED

As per guidelines CPU security level should be dropped before OS start,
so that certain MSRs are locked out. Drop privilege levels on all logical
CPUs.

BUG=chrome-os-partner:60454
TEST=iotools rdmsr x 0x120, make sure bit 6 is set, rdmsr x 0x121 results
in io error.
