Add the DPI/RGB input pixel clock in mandatory properties
because it really offers a better preciseness for timing
computations.

Please apply "dt-bindings: display: stm32: correct clock-names
in dsi panel example" before this patch.
Changes in v3: remove the note regarding swapped clock names
(now in a separate patch).
Changes in v2: put new clock in last position (Rob Herring)
