arm: dts: lx2160aqds: add nodes describing possible mezzanine cards

Add device trees describing possible uses of mezzanine cards depending
on the SERDES protocol employed.

This patch adds DPAA2 networking support for the following protocols on
each SERDES block:
 * SD #1: 3, 7, 19, 20
 * SD #2: 11

Each SERDES block has a different device tree file per protocol
supported, where the IO SLOTs used are enabled and PHYs located on the
mezzanine cards are described. Also, dpmac nodes are edited and their
associated phy-connection-type and phy-handle are added.

Top DTS files are also added for each combination of protocol on the 3
SERDES blocks.
