[U-Boot] [UBOOT RFC PATCH 00/13] DRA7xx: Add DWC3 USB driver and enable DFU

[Kishon Vijay Abraham I]

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.
