PCI: apple: Do not leak reset GPIO on unbind/unload/error
The driver allocates reset GPIO in apple_pcie_setup_port() but neither
releases the resource, nor uses devm API to have it released
automatically.
Let's fix this by switching to devm API. While at it let's use generic
devm_fwnode_gpiod_get() instead of OF-specific gpiod_get_from_of_node()
- this will allow us top stop exporting the latter down the road.
