soc/intel/apollolake: Add SGX support

- Call into commmon SGX code to configure core PRMRR
and follow other SGX init seqeuence.
- Report correct cbmem top with PRMRR enabled
- Enable SOC_INTEL_COMMON_BLOCK_SGX for both APL/GLK, so that
build does not break.
- Enable SOC_INTEL_COMMON_BLOCK_CPU_MPINIT for GLK, as MP init needs
to be completed before calling into fsp-s for SGX.
