target/pscsi: Convert to external pscsi_backend_dev_attrs
This patch converts PSCSI to use an external set of device attributes,
and utilizes target_core_backend_configfs.h macros to generate a default
set of configfs extended-attr handlers.
It calls target_core_setup_sub_cits() to setup the initial config_item_type
based on existing target_core_configfs.c defaults, and using configfs_attribute
for hw_pi_prot_type, hw_block_size, hw_max_sectors, hw_queue_depth populates
pscsi_backend_dev_attrs[]
Only these four hw_* read-only device attributes are exports for PSCSI.
