soc/intel/apollolake: Select CPU_INTEL_COMMON

This is an intermediate step to have SOC_INTEL_COMMON_BLOCK_CPU select
CPU_INTEL_COMMON directly, to avoid dependency problems.

Tested with BUILD_TIMELESS=1, UP Squared does not change.
Gemini Lake already selects this through SOC_INTEL_COMMON_BLOCK_SGX.
