On i.MX6Q/6DL the following subnodes exist to describe the CSI port muxing:
- ipu1_csi0_mux
- ipu1_csi1_mux
- ipu2_csi0_mux
- ipu2_csi1_mux
As they were not documented, dt-schema emits warnings like:
'ipu1_csi0_mux', 'ipu1_csi1_mux' do not match any of the regexes:
'^pinctrl-[0-9]+$'
Add a top-level patternProperties entry for these CSI mux subnodes.

Need disallow it for other compatible string
allOf:

properties:
compatible:
not:
contains:
const: fsl,imx6q-iomuxc-gpr
then:
