Subject: [BUG] Regression, usb-dwc3 not working, Odroid XU3, usb 3.0

Hi,


Since three recent next releases (first on 20160630), on Odroid XU3 board
the USB 3.0 host port (the only one) stopped working.

This is a "samsung,exynos5250-dwusb3" (drivers/usb/dwc3/dwc3-exynos.c).

Two issues here:
1. The port does not show up as USB 3.0 device.
This one device is missing:
	Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

2. The port does not work even for 2.0 devices (I didn't test 1.0).


config: exynos_defconfig (ARM)
DTS: exynos5422-odroidxu3.dts
