Subject: [PATCH v3 2/7] dt-bindings: net: snps,dwmac: Update the maxitems number of resets and reset-names

Some boards(such as StarFive VisionFive v2) require more than one value
which defined by resets property, so the original definition can not
meet the requirements. In order to adapt to different requirements,
adjust the maxitems number definition.
