The new rk3288 revision rk3288w has some changes with respect to legacy rk3288 like hclk_vio in cru and usb host0 ohci. Linux clock driver already handle this via rockchip,rk3288w-cru compatible. USB ohci host can enable via dts for rk3288w based boards. So, add fdt board setup code to update cru compatible with rk3288w-cru compatible if the SOC revision is RK3288W.
