Adapt the usb-compat.h to uBoot.
Use #ifndef __UBOOT__ for code that is not applicable to uBoot. Use #ifdef __UBOOT__ to add code that is uBoot specific.
Create linux-compat.h - Linux kernel compatibility definitions that do not exist in the uBoot. Moved the compatibility definitions from lin_gadget_compat.h to this file as well.
Create usb-mod-devicetable.h - Is a partial back port of mod_devicetable.h in the linux kernel only taking the portion needed for USB
Already existing header files were modified to pick up the new header files.

Are these warnings that aren't applicable to us, or things that need to be fixed as part of the series, eventually?
But, in general, as this is the approach I suggested, I'm fine with it.
