arm64: dts: fsl-ls1028a: prepare dts for overlay

Named the ports node of the Felix Eth switch so it can be used in DT
overlays to associate the ports with proper PHYs.
Ports are now by default disabled in dtsi, so if the board dts doesn't
do anything about them they stay disabled.
Updated RDB and QDS dts files to match.
Replaced all 'phy-connection-type' with 'phy-mode'.
The set-up for protocol 7777 on QDS was changed to a single quad port card
in slot 1.  This requires a QDS board with no lane B rework and a AQR412
or similar PHY card without any lane rework done on it.
