I don't believe that would be conventional. '-gpios' seems to be the
standard over '-gpio' even for a single GPIO.

Having multiple GPIOs in that field is only relevant when it could be an
array e.g. multiple chip-select GPIO lines. Not for multiple GPIOs with
differing functions.

Also it doesn't fit with the way devm_gpiod_get works where you select
GPIO(s) from the device-tree, and specify whether it's an input or an
output. In this case one is an output, one is an input.
