Add support for DU on r8a779g0, which is identical to DU on r8a779a0.

Given that this is the V4H ... I wonder if this should be bumped
already. I guess that has knock on effects through the driver though...

rcar_du_group_setup_didsr() would need to be fixed to test gen >= 3
instead of gen == 3. That seems to be the only problematic location. It
could thus fairly easily be done in v2, but we can also delay it.

Ok, I can fix that here.
