gpiolib: Extend software-node support to support secondary software-nodes
When a software-node gets added to a device which already has another
fwnode as primary node it will become the secondary fwnode for that
device.
Currently if a software-node with GPIO properties ends up as the secondary
fwnode then gpiod_find_by_fwnode() will fail to find the GPIOs.
Add a new gpiod_fwnode_lookup() helper which falls back to calling
gpiod_find_by_fwnode() with the secondary fwnode if the GPIO was not
found in the primary fwnode.
Fixes: e7f9ff5dc90c ("gpiolib: add support for software nodes")
