dt-bindings: arm: fsl: Add solidrun lx2160a twins board

The SolidRun LX2160A Twins board supports two configurations, one with
with a single CEX-7 module, and one with two (dual).

The single configuration is a specific assembly that maximises
connectivity for single cpu by routing some second cpu resources to the
first via zero-Ohm resistors.

The dual configuration was not yet tested and is intentionally omitted.

Initial review strongly suggests that the dual configuration will have
different bindings, because from either cpu point of view the board
appears different (e.g. different number of sfp, fewer i2c gpio).

Add binding for the single variant only.
