The driver only needs the reset GPIO for a very brief period, so instead
of using devres and keeping the descriptor pointer inside priv, just use
that descriptor inside the sja1105_hw_reset function and then let go of
it.
Also use gpiod_get_optional while at it, and error out on real errors
(bad flags etc).
