dt-bindings: clocks: add rk3288w variant compatible

Browse source 
Add the possible compatible "rockchip,rk3288w-cru" that handles
the difference between the rk3288 and the new revision rk3288w.

This compatible will be added by bootloaders.

@ -4,9 +4,15 @@ The RK3288 clock controller generates and supplies clock to various
controllers within the SoC and also implements a reset controller for SoC
peripherals.
A revision of this SoC is available: rk3288w. The clock tree is a bit
different so another dt-compatible is available. Noticed that it is only
setting the difference but there is no automatic revision detection. This
should be performed by bootloaders.
Required Properties:
- compatible: should be "rockchip,rk3288-cru"
- compatible: should be "rockchip,rk3288-cru" or "rockchip,rk3288w-cru" in
case of this revision of Rockchip rk3288.
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
