There is a new CPRB minor version T7 to be supported with this patch. Together with this the functions which extract the CPRB data from userspace and prepare the AP message do now check the CPRB minor version and provide some info in the flag field of the ap message struct for further processing. The 3 functions doing this job have been renamed to prep_cca_ap_msg, prep_ep11_ap_msg and prep_rng_ap_msg to reflect their job better (old was get..fc). This patch also introduces two new flags to be used internal with the flag field of the struct ap_message: AP_MSG_FLAG_USAGE is set when prep_cca_ap_msg or prep_ep11_ap_msg come to the conclusion that this is a ordinary crypto load CPRB (which means T2 for CCA CPRBs and no admin bit for EP11 CPRBs). AP_MSG_FLAG_ADMIN is set when prep_cca_ap_msg or prep_ep11_ap_msg think, this is an administrative (control) crypto load CPRB (which means T3, T5, T6 or T7 for CCA CPRBs and admin bit set for EP11 CPRBs).
