[PATCH v4 2/6] usb: dwc3: dwc3-octeon: Pass dwc3_octeon to setup functions

[Ladislav Michl <oss-lists@triops.cz>]

From: Ladislav Michl <ladis@linux-mips.org>

Pass dwc3_octeon instead of just the base. It fits with the
function names and it requires less change in the future if
access to dwc3_octeon is needed.
