PCI: tegra: Switch to using devm_fwnode_gpiod_get

[devm_]gpiod_get_from_of_node in drivers usage should be limited
so that gpiolib can be cleaned up; 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.
