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.
