rockchip: rk3288: Add OF board setup

Browse Source 
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.
