dt-bindings: display: renesas,du: Add r8a779h0 



Extend the Renesas DU display bindings to support the r8a779h0 V4M.

Note that we remove the requirement for two ports from the global part
of the bindings, as each conditional part defines the number of required
ports already. This came up with r8a779h0 as it's the first one that has
only one port.
