[U-Boot] [PATCH] usb:gadget: Disallow DFU in SPL for now

[Tom Rini]

Previously, DFU was not built in for SPL and often disabled via the board
config.h file, in the SPL build.  By moving DFU to Kconfig we now need to
move this logic to the Makefile to continue to allow boards to fit within
their SPL size limit (until gcc 6 is more widespread and unused strings will
be discarded).

Without this, but everything converted am335x_evm_usbspl fails to link (does
gadget USB in SPL) unless we make drivers/dfu/ unconditional.  This however
breaks a few other platforms that have a smaller SPL size due to undiscarded
strings, and a lot of other platforms just grow by a few KiB.  This is the best
solution I can come up with for now.
