usb_port_power_dumb: allow board to customize hooks
On Asurada, some Sandisk stickers would enter fault status
(down-train to USB2 or not detected) if Vbus is applied before xhci
initialization. The defauilt S3 hooks does not work in this case.
This CL adds a config option to allow board to control the timing to
enable/disable port power.
