Document DU found in RZ/G2UL SoC. The DU block is identical to RZ/G2L
SoC, but has only DPI interface.
While at it, add missing required property port@1 for RZ/G2L and RZ/V2L
SoCs. Currently there is no user for the DPI interface and hence there
won't be any ABI breakage for adding port@1 as required property for
RZ/G2L and RZ/V2L SoCs.

v3->v4:
* Restored the ports property for RZ/G2UL and described port@0 for the
DPI interface.
* Restored tags from Geert and Conor as the change is trivial
(Replaced port 1->0 from v2).
v2->v3:
* Replaced ports->port property for RZ/G2UL as it supports only DPI.
and retained ports property for RZ/{G2L,V2L} as it supports both DSI
and DPI output interface.
* Added missing blank line before example.
* Dropped tags from Conor and Geert as there are new changes.
v1->v2:
* Updated commit description related to non ABI breakage.
* Added Ack from Conor.
