Subject: [PATCH 3/7] arm64: dts: mediatek: mt8195: add ethernet device node

From: Biao Huang <[email protected]>

This patch comes from https://lore.kernel.org/all/[email protected]/

The differences between that patch and this patch is that:
* The EVB dts modification has been split into its own commit
* The patch was rebased to fix merge conflict with the upstream mt8195.dtsi file
* Re-ordered the node to be correctly sorted based on node address
