This series converts dwc3 peripheral to device model and the best way to
test this on TI platform to use it on ether gadget and test RNDIS boot.
Hence, I had to do patches 8 to 13. Therefore I posted them together for
completeness, if somebody wanted to test this out.

eth*addr is used for regular ethernet interface and usually set by
regular ethernet driver, but I could not find a way to set MAC address
for usb ethernet interface
Board file will now override board_set_usbnet_devaddr() to read MAC and
then call setenv()
