add dfu supprt for at91 sam9260 based boards. The USB gadget driver is ported from linux:
b2ba27a5c56ff: usb: gadget: at91_udc: move prepare clk into process context
it drops a lot of checkpatch warnings/errors:
checkpatch.pl found 12 error(s), 31 warning(s), 43 checks(s)
but for further updates I did not fix them. The errors are all from this sort:
error: drivers/usb/gadget/at91_udc.c,87: space prohibited before open square bracket '['
a lot of "line over 80 characters" warnings ...
