usb: host: xhci: skip phy init quirk can configure in dt

Browse Source 
The "skip_phy_initialization" property in usb_hcd structure means
that do not manage the PHY state in the HCD core and handle it by
the controller's driver. This commit adds "quirk-skip-phy-init"
quirk which can configure the property in DT to support it.

For Rockchip DWC3 dual role scheme, we enabled the device wakeup
capability in dwc3 runtime resume that would cause the PHY exit
failed in "usb_phy_roothub_exit()" at PM suspend stage. So this
commit is also a workaround to fix it.
