From: Vadim Bendebury <vben...@chromium.org>

Exynos5800 IROM has a different, from 5250 and 5420, prototype of the
usb_copy() function. Luckily the earlier version did not expect any
arguments, which means the same code could be used with old and new
SoCs, the old ones just ignoring the arguments.
