Nicholas Bellinger 2ed22c9cbc 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
