arm64: dts: lx2162a: transition to device-specific SerDes compatible strings

Browse Source 
Align to the modern fsl,lynx-28g.yaml binding for the LX2162A SoC, where
the SoC and SerDes instance is present in the compatible string, to
allow reliable per-lane capability detection and per-lane customization
of electrical properties.

Since one of the major differences between LX2162A and LX2160A is the
SerDes, add the necessary nodes to its own fsl-lx2162a-serdes.dtsi file.

Also mark the serdes_1 node as disabled by default since any dts using
it enables it explicitly now.
