[media] sh-mobile-ceu-driver: support max width and height in DT 



Some CEU implementations have non-standard (larger) maximum supported
width and height values. Add two OF properties to specify them.

Bindings, specific for the sh_mobile_ceu_camera.c driver:

 - compatible: Should be "renesas,sh-mobile-ceu"

 - reg: register base and size

 - interrupts: the interrupt number

 - interrupt-parent: the interrupt controller

 - renesas,max-width: maximum image width, supported on this SoC

 - renesas,max-height: maximum image height, supported on this SoC



Example:



ceu0: ceu@0xfe910000 {

	compatible = "renesas,sh-mobile-ceu";

	reg = <0xfe910000 0xa0>;

	interrupt-parent = <&intcs>;

	interrupts = <0x880>;

	renesas,max-width = <8188>;

	renesas,max-height = <8188>;

};
