Document support for Airoha AN8855 5-port Gigabit Switch.

It does expose the 5 Internal PHYs on the MDIO bus and each port
can access the Switch register space by configurting the PHY page.

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.
