[PATCH net v3] dt-bindings: ethernet: eswin: fix hsp-sp-csr backward compatibility

[PATCH net v3] dt-bindings: ethernet: eswin: fix hsp-sp-csr backward compatibility

[lizhi2]

From: Zhi Li <lizhi2@eswincomputing.com>

Commit c36069c6f46c ("dt-bindings: ethernet: eswin: add optional TXD and
RXD delay register offsets") added two optional cells to eswin,hsp-sp-csr
but omitted minItems: 4.

As a result, dt-schema implicitly required all 6 cells, which broke
backward compatibility with existing 4-cell device trees.

Add minItems: 4 to preserve backward compatibility.
