f6fcebf5c1 usb: udc: Fix warnings on 64-bit builds
Cast u32 bit value to 64bit before recasting to 64bit pointer to avoid
pointer from integer cast size mismatch warnings.

Warning log:
+../drivers/usb/gadget/udc/udc-core.c: In function
‘usb_gadget_unmap_request’:
+../drivers/usb/gadget/udc/udc-core.c:68:19: warning: cast to pointer
from integer of different size [-Wint-to-pointer-cast]

103fa06cfe usb: gadget: udc: make udc-core compile in u-boot build
Make udc-core compile in u-boot by removing all linux specific
stuff and having only the bare minimal udc-core required for
usb gadget drivers. Also modified the file header to a format that is
generally being used in u-boot.

a139b96a47 usb: gadget: udc: add udc-core from linux kernel to u-boot
Added udc-core.c from linux kernel 3.19-rc1 (97bf6af1f9) to u-boot.
This will be adapted to work with u-boot in the
following patches.
Adding support for udc will help to seamlessly port dwc3 driver from
linux kernel to u-boot (since dwc3 uses udc-core) and it'll also help
to add support for multiple gadget controllers to be functional at the
same time.
All other gadget drivers can also be adapted to use udc-core.
