The generic operating points specified in rk3288.dtsi are specified by Rockchip as conservative and for all cases. The Tinker Board / S devices use a special chip variant called rk3288-c and use different operating points with a higher max frequency. So add the missing operating points for Tinker Board / S devices, also increase the regulator-max-microvolt to 1400000 so that the cpu can operate at 1.8 GHz.
