[U-Boot] [PATCH v4 7/7] Peach-Pi: Use the enhanced usb_copy() prototype

[Akshay Saraswat]

From: Vadim Bendebury <vbendeb at 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.
