 armada 388 clearfog boards

Hello Josua Mayer,

> Dear Maintainers,
>
> The initially merged device-tree for Clearfog GTR devices contained
> various subtle mistakes and omissions:
>
> - missing board-specific compatible strings
> - missing pinctrl entries
> - missing second sfp connector
> - invalid sfp loss-of-signal gpio
> - mismatch of labels between dsa ports and enclosure
>
> Most notably this had caused functional issues with the sfp connectors.
>
> This patch-set first converts the existing armada-38x dt-bindings to
> yaml, replacing invalid soc-only compatibles with specific boards that
> already exist in tree and represent the three SoCs (380,385,388).
>
> Secondly for clearfog gtr pinctrl nodes are added for all referenced
> gpios for independence from bootloader defaults. U-Boot is shared
> between armada-388 clearfog and armada-385 clearfog gtr.
>
> Further remove an invalid io from the first sfp connector description,
> and add descriptions for the secondary sfp connector which is driven
> by dsa switch port number 9.
>
> Finally labels of dsa switch ports were updated to match the enclosure.
> That patch is not suitable for stable.

Rebased on v6.8-rc1, fixed merge conflict and applied on mvebu/dt

Thanks,
