target: Add DIF related base definitions
This patch adds DIF related definitions to target_core_base.h that includes enums for target_prot_op + target_prot_type + target_prot_version + target_guard_type + target_pi_error. Also included is struct se_dif_v1_tuple, along with changes to struct se_cmd, struct se_dev_attrib, and struct se_device. Also, add new se_subsystem_api->[init,format,free]_prot() callers used by target core code to setup backend specific protection information after the device has been configured. Enums taken from Sagi Grimberg's original patch. v2 changes: - Drop guard_type related definitions - Update target_prot_op + target_prot_ho definitions (Sagi) - Drop SCF_PROT + pi_prot_version flag - Add se_subsystem_api->format_prot() (Sagi) - Add hw_pi_prot_type device attribute Cc: Martin K.
