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

From: Peter Chen <redacted> 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. Signed-off-by: Peter Chen <redacted> Signed-off-by: Maciej S.
