drm/pl111: add of_node_put()

of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. bl_idle_init() doesn't do that, so fix it.

The "bl_idle_init" appeared to be copy-and-paste from some other commit message, so I droppped that bit and pushed. Thanks!
