arm64: dts: clearfog-gt-8k: set gigabit PHY reset deassert delay
If the mv88e6xxx DSA driver is built as a module, it causes the ethernet driver to re-probe when it's loaded. This in turn causes the gigabit PHY to be momentarily reset and reprogrammed. However, we attempt to reprogram the PHY immediately after deasserting reset, and the PHY ignores the writes. This results in the PHY operating in the wrong mode, and the copper link states down. Set a reset deassert delay of 10ms for the gigabit PHY to avoid this.
