TX2 DTS modifications for USB/PCIe lane mapping config 4 (r32.1)

We have a custom board designed for USB/PCIe Config 4 lane mapping, with three USBs. What device-tree modifications do i need to do to enable Config 4, for L4T r32.1?



Most of them should be same as rel-28 case.

Only the pinctrl part is different. “pinctrl@3520000” is no longer needed. Please also refer to the adaptation guide for Nano or Xavier as reference. The way to configure usb is universal now, so all platforms are same.
