dt-bindings: net: dwmac: Increase 'maxItems' for 'interrupts' and 'interrupt-names' 



Increase the `maxItems` value for the `interrupts` and `interrupt-names`
properties to 11 to support additional per-channel Tx/Rx completion
interrupts on the Renesas RZ/V2H(P) SoC, which features the
`snps,dwmac-5.20` IP.

Refactor the `interrupt-names` property by replacing repeated `enum`
entries with a `oneOf` list. Add support for per-channel receive and
transmit completion interrupts using regex patterns.
