Subject: [PATCH 1/3] dt-bindings: net: dwmac: Increase 'maxItems' for 'interrupts' and 'interrupt-names'

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Increase the `maxItems` value for the `interrupts` and `interrupt-names`
properties to accommodate the Renesas RZ/V2H(P) SoC, which features the
`snps,dwmac-5.20` IP with 11 interrupts.

Also add `additionalItems: true` to allow specifying extra interrupts
beyond the predefined ones. Update the `interrupt-names` property to
allow specifying extra `interrupt-names`.

Also refactor the optional `interrupt-names` property by consolidating
repeated enums into a single enum list.
