[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>;
};
