MAINTAINERS: update intel,ixp46x-rng.yaml reference
The file name: Documentation/devicetree/bindings/display/intel,ixp46x-rng.yaml
should be, instead: Documentation/devicetree/bindings/rng/intel,ixp46x-rng.yaml.
Update its cross-reference accordingly.
Fixes: cca061b04c0d ("hw_random: ixp4xx: Add DT bindings")
