[PATCH v3 03/11] arm64: dts: lx2160a: extract the SerDes nodes into a separate dtsi

[Ioana Ciornei]

In terms of its SerDes blocks, the LX2162A is not properly described
since it just inherits the LX2160A SerDes nodes, which is not correct.
In order to fix this but also avoid the usage of delete-node, we need to
first extract the SerDes nodes currently found in fsl-lx2160a.dtsi into a
separate dtsi.

This patch does not intend to do any actual changes in the final dtb
files, only a dt node move.
