Subject: [PATCH v1 01/11] PCI: tegra: switch to using devm_fwnode_gpiod_get

I would like to limit (or maybe even remove) use of
[devm_]gpiod_get_from_of_node in drivers so that gpiolib can be cleaned
a bit, so let's switch to the generic device property API. It may even
help with handling secondary fwnodes when gpiolib is taught to handle
gpios described by swnodes.
