[PATCH] dt-bindings: soc: imx-iomuxc-gpr: Document the CSI mux

[Fabio Estevam]

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.
