Log:
  dwc: Add more delay for chip reset
  
  On rockchip board it seems that the value in the DTS
  are not enough for reseting the chip, I don't know if
  the value are really incorrect or if DELAY is not precise
  enough or if the rockchip gpio driver have some "lag" of some
  kind or not.
  For now just add more delay.
