Subject: [PATCH] dmaengine: idxd: Remove unused idxd_(un)register_bus_type

From: "Dr. David Alan Gilbert" <linux@...blig.org>

idxd_register_bus_type() and idxd_unregister_bus_type() have been unused
since 2021's
commit d9e5481fca74 ("dmaengine: dsa: move dsa_bus_type out of idxd driver
to standalone")

Remove them.
