arm64: dts: fsl-ls1028a-qds: Add overlays for various serdes protocols

Adds overlays for various serdes protocols on LS1028A QDS board using
different PHY cards.  These should be applied at boot, based on serdes
configuration.  If no overlay is applied, only the RGMII interface on
the QDS is available in Linux.
