[PATCH V2] gpio: Fix return value mismatch of function gpiod_get_from_of_node()

In case the requested gpio property is not found in the device tree, some callers of gpiod_get_from_of_node() expect a return value of NULL, others expect -ENOENT. In particular devm_fwnode_get_index_gpiod_from_child() expects -ENOENT. Currently it gets a NULL, which breaks the loop that tries all
