soc/intel/common/pch: Add a block specific to Apollo Lake

Add SOC_INTEL_COMMON_PCH_CLIENT which is specific to Apollo
Lake. This is used to select the options that Apollo Lake
requires, without the ones specific to a PCH as Apollo Lake
doesn't have a PCH.

This change also enables SOC_INTEL_COMMON_PCH_LOCKDOWN for
Apollo Lake.
