To: u-boot
The K2G evm uses the generic DWC3 driver. DFU can thus be enabled.
Enabling DFU for easier firmware update.
Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>

Changes in v2:
- rebased on latest version of u-boot-usb/master
- use DM_USB_GADGET instead of DM_USB_DEV

I'm not sure if I shall wait for Marek's PR to Tom (preferred) or send
new PR to Marek?
Marek what do you think?
