From: Lad Prabhakar <[e-mail]>

The DU block on the RZ/V2H(P) SoC is identical to the one found on the
RZ/G2L SoC. However, it only supports the DSI interface, whereas the
RZ/G2L supports both DSI and DPI interfaces.

Due to this difference, a SoC-specific compatible string
'renesas,r9a09g057-du' is added for the RZ/V2H(P) SoC.

This goes probably after the if: block for renesas,r9a07g043u-du to keep
sorting (if I get numbers correctly).
