After recent changes to fw_devlink that ended with commit 4a032827daa8
("of: property: Simplify of_link_to_phandle()"), fw_devlink no longer
cares about the "compatible" property and figures out the correct struct
device at runtime. So, we no longer need to call
fw_devlink_purge_absent_suppliers().
