[PATCH 2/3] ARM: dts: imx6qdl-udoo.dtsi: fix onboard USB HUB property

From: Peter Chen <peter.chen at nxp.com>

The current dts describes USB HUB's property at USB controller's
entry, it is improper. The USB HUB should be the child node
under USB controller, and power sequence properties are under
it.
