soc/intel/cnl: lock AES-NI feature if selected
Lock AES-NI (MSR_FEATURE_CONFIG) to prevent unintended changes of
AES-NI enablement as precaution, as suggested in Intel document
325384-070US.
Locking is enabled by default (as already done in SKL and Arrandale) and
may be disabled by the newly introduced Kconfig in the parent change.
Tested by checking the MSR.
