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
and restrict it to i.MX6Q.
Signed-off-by: Fabio Estevam <festevam@gmail.com>

Changes since v1:
- Restrict it to i.MX6Q (Frank).
