gpio: swnode: don't use the swnode's name as the key for GPIO lookup

[ Upstream commit e5d527be7e ]

Looking up a GPIO controller by label that is the name of the software
node is wonky at best - the GPIO controller driver is free to set
a different label than the name of its firmware node. We're already being
passed a firmware node handle attached to the GPIO device to
swnode_get_gpio_device() so use it instead for a more precise lookup.
