This symbol is not used outside of panfrost_drv.c, so marks it static.
Fix the following sparse warning:

Currently it66121_probe returns -EPROBE_DEFER if the there is no remote
endpoint found in the device tree which doesn't seem helpful, since this
is not going to change later and it is never checked if the next bridge
has been initialized yet. It will fail in that case later while doing
