usb: dwc3: apply snps,host-vbus-glitches workaround unconditionally

Remove 'snps,host-vbus-glitches-quirk' and apply workaround
unconditionally.

It is safer to keep vbus disabled before handing over to xhci driver. So
needn't 'snps,host-vbus-glitches' property to enable it and apply it
unconditionally.

Remove all host_vbus_glitches variable and call
dwc3_power_off_all_roothub_ports() directly.
