Subject: [PATCH 1/2] dt-bindings: media: i2c: add galaxycore,gc2145 DVP bus support

Don't require link-frequencies like it's done for ov5640, that
supports both CSI-2 and DVP. And v4l2_fwnode_endpoint_alloc_parse
ignores link-frequencies property for DVP endpoint. It's used only for
CSI-2 endpoints
