Subject: [PATCH] remoteproc: Move rproc_delete_debug_dir() to rproc_del()

The "remoteproc{0,1...}" sysfs entries are added in
rproc_add() and deleted in rproc_type_release() instead of
in rproc_del(). That leaves these lingering entries sticking
around after we return from rproc_del(). Move the
rproc_delete_debug_dir() to rproc_del() to fix this.
