Rockchip SoC's has a new revision chip for rk3288 SoCs. RK3288 has a new revision chip called RK3288W which is similar but different hclk_vio clock and fixed OHCI host. Add common Rockchip SoC detection helper to support this rk3288w detection. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
