dt-bindings: media: nxp,imx7-mipi-csi2: Drop bad if/then schema
The if/then schema for 'data-lanes' doesn't work as 'compatible' is at a
different level than 'data-lanes'. To make it work, the if/then schema
would have to be moved to the top level and then whole hierarchy of
nodes down to 'data-lanes' created. I don't think it is worth the
complexity to do that, so let's just drop it.
The error in this schema is masked by a fixup in the tools causing the
'allOf' to get overwritten. Removing the fixup as part of moving to
json-schema draft 2019-09 revealed the issue:
Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@30750000: ports:port@0:endpoint:data-lanes:0: [1] is too short
From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml
Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@32e30000: ports:port@0:endpoint:data-lanes:0: [1, 2, 3, 4] is too long
From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml
The if condition was always true because 'compatible' did not exist in
'endpoint' node and a non-existent property is true for json-schema.
