This converts the USB3503 to pick GPIO descriptors from the device tree instead of iteratively picking out GPIO number references and then referencing these from the global GPIO numberspace. The USB3503 is only used from device tree among the in-tree platforms. If board files would still desire to use it they can provide machine descriptor tables. Make sure to preserve semantics such as the reset delay introduced by Stefan.
