[v2,10/52] dt-bindings: display: Move idk-1110wr to panel-lvds

The Advantech IDK-2121WR Device Tree binding doesn't really add any
useful content that is not already present in the panel-lvds binding
aside from a requirement on the data-mapping.

Let's move it to the generic panel-lvds binding

I'm concerned this change means we can only have LVDS panel schemas in 
lvds.yaml. Having another LVDS panel schema means 2 things. First, they 
can't have a 'panel-lvds' compatible. That's probably fine. Second, they 
will still need to define 'data-mapping' (unless implied) and will need 
to include it from somewhere. So we still need a common LVDS properties 
schema and panel schema(s).
