Do you mean just dropping these two lines (and MaxItems: 1), and leaving
"reg" in "required" and in the example? E.g.:
...
required:
- compatible
- reg
- clocks
- clock-names
- port

additionalProperties: false

examples:
- |
#include <dt-bindings/gpio/gpio.h>
#include <dt-bindings/clock/imx6qdl-clock.h>

i2c {
#address-cells = <1>;
#size-cells = <0>;

ar0521: camera-sensor@36 {
compatible = "onnn,ar0521";
reg = <0x36>;
pinctrl-names = "default";

...

It protests with:

Documentation/devicetree/bindings/media/i2c/onnn,ar0521.example.dt.yaml:
camera-sensor@36: 'reg' does not match any of the regexes: 'pinctrl-[0-9]+'
From schema: /usr/src/linux/imx6/Documentation/devicetree/bindings/media/i2c/onnn,ar0521.yaml

Thus I'm currently leaving it as is.
