[PATCH v3 0/5] dt-bindings: convert timing + panel-dpi to DT schema

This set of patches convert display-timing.txt to DT schema.
To do that add a panel-timing.yaml file that include all the
panel-timing properties and use this in panel-common and in display-timings.

panel-dpi was also converted so we have no .txt users left of panel-timing
in panel/

Everything passed dt_binding_check - and the trivial errors I tried in
the examples was all catched during validation.

This work was triggered by a patch-set from Oleksandr Suvorov aiming
at updating panel-lvds to support panel-dpi.
This will make it simple to add additional properties to panel-dpi.

Thanks for the quick responses on v2 and likewise the quick
feedback on the request for the license change!

Highlight from v3 - se individual patches for details.
- Added panel-dpi support to panel-simple.
  We can now add a simple panel just by addding timing parameters
  in a DT node
  The patch [5/5] is RFC as test is pending
- To support panel-dpi in panel-simple - add a data-mapping
  property to panel-dpi

Highlights from v2 - see individual patches for details.
- Got acks for the license change
- Simplfied panel-timings bindings
- panel-dpi can now be used without a panel specific compatible
  So panel-dpi can be used as a generic binding for dumb panels

Feedback welcome!
