cns3xxx: fix dwc_otg driver compat with udc-core
function. This removes those from the dwc_otg driver and removes the patch that comments out the linkage of udc-core so that the dwc_otg driver can co-exist happily with other USB Device Controllers. Signed-off-by: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 34475

A USB device uses a controller to talk to its host.
Systems should have only one such upstream link.
