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
