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.
