[PATCH] ARM: dts: imx6qdl-udoo: Disable usbh1 to avoid kernel hang

Currently the kernel hangs when USB Host1 is enabled due to the lack of
support for controlling the USB hub clock and GPIO reset line.

Peter Chen has made several attempts to fix this problem, but his series
has not been applied yet, so better disable USB host1 for now to avoid
the kernel hang.
