At the moment, the preparation of GUC_CTL_LOG_PARAMS is disordered.
Additionally, in struct intel_guc_log we have an unnecessary field
'flags' which we use only to assign value to GuC parameter.
Lets move all GUC_CTL_LOG_PARAMS related operations to one place,
and lets remove field 'flags' from struct intel_guc_log.
