Ported DWC3 driver from linux kernel v3.16 to uboot and enabled DFU in DRA7xx. Tested only with DFU ram.
While I kept the dwc3 driver pretty much the same from linux kernel, I have created a single driver for both USB2 and USB3 PHY programming. I have also adapted udc-core from linux kernel so that we can cleanly link the gadet driver with the controller driver.

Merge branch 'master' of git://git.denx.de/u-boot-usb
Let me know of any feedback and suggestions.
Known Issues: DWC3 is not enumerating consistently.
