So far, the binding and driver have relied on the fact that the H6 clocks are both a prefix and a subset of the R40 clocks. This allows them to share the clocks/clock-names items and the clock-output-names order between the hardware variants.
However, the D1 hardware has TCON TV0 and DSI, but no TCON TV1. This cannot be supported by the existing scheme because it puts a gap in the middle of the item lists. To prepare for adding D1 support, use separate lists for variants with different combinations of clocks.
