From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>
[ Upstream commit 9c2cc7171e08eef52110d272fdf2225d6dcd81b6 ]
The controller is using non-standard "reset-n-io" name for its reset
gpio property, whereas gpiod API expects "<name>-gpios". Add a quirk
so that gpiod API will still work on unmodified DTSes.
