ARM: mmp: add usb device support for ttc dkb
There is an U2O OTG controller on ttc dkb, this patch is going to enable it. At this moment, it can only works in device mode, because when works in host mode, it needs to supply vbus, but we have no vbus driver added at this moment. Once the vbus driver is added, I'll prepar another patch to enable the switch function. Signed-off-by: Neil Zhang <zhangwm@marvell.com> Signed-off-by: Haojian Zhuang <haojian.zhuang@gmail.com>
