[PATCH] usb_hub: Set DM_FLAG_DEFAULT_PD_CTRL_OFF to usb_hub driver

[Ye Li]

Because usb_hub uses same device tree node with USB controller device,
when probe and remove usb_hub, it will call the power domain control of
USB controller device.
This is not expected, because power domain control implmentation may not
have count when the power domain is dedicated for USB controller. So once
removed usb_hub, the power domain is power off before removing USB controller.
