I'm not sure if topic should be about USB-C, I will call it simply USB
connector node. TM2(e) uses Samsung's 11-pin micro USB 2.0 connector,
which has nothing in common with USB Type-C.
Anyway, this patch breaks DWC3 (tested in Device mode) driver operation,
so something has to be somehow adjusted or fixed. Added CC Andrzej
Hajda, who actually worked on this.
