arm: dts: ls1028a: define QDS networking protocol combinations

Includes DT definition for the following serdes protocols using various
PHY cards: 85xx, 13xx, 65xx, 9999, 7777.

Note that the default device tree for QDS now uses 85xx.
Enabling any of the others requires patching the fsl-ls1028a-qds.dtsi
file (the includes at the bottom of the file).

The phy-handle is specified as a path rather than a label because it is
possible to use the #include multiple times (meaning that more than one
PHY riser card of one type is inserted), and therefore, there would be
duplicate labels with the same name.

LBRW means that the board needs lane B rework before using this dtsi.
