This patch adds the necessary OF alias for the UDC node, which let's the code locate the DWC2 UDC base address in OF instead of hard-coding it into the U-Boot binary. The code is adjusted to use the address from OF instead of the hard-coded one. Finally, the hard-coded address is removed and USB DM support is enabled.
