platform/x86: ISST: Process read/write blocked feature status

Browse source

When a feature is read blocked, don't continue to read SST information
and register with SST core.

When the feature is write blocked, continue to offer read interface for
SST parameters, but don't allow any operation to change state. A state
change results from SST level change, feature change or class of service
change.
