[PATCH 12/12] ARM: dts: imx6qdl-udoo.dtsi: fix onboard USB HUB property

From: Peter Chen <peter.chen@freescale.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, with "usb-pwrseq" phandle to handle power
sequence stuffs.
