target/configfs: Expose protection device attributes
This patch adds support for exposing DIF protection device attributes via configfs. This includes: pi_prot_type: Protection Type (0, 1, 3 currently support) pi_prot_format: Protection Format Operation (FILEIO only) Within se_dev_set_pi_prot_type() it also adds the se_subsystem_api device callbacks to setup per device protection information. v2 changes: - Drop pi_guard_type + pi_prot_version related code (MKP) - Add pi_prot_format logic (Sagi) - Add ->free_prot callback in target_free_device - Add hw_pi_prot_type read-only attribute Cc: Martin K.
