This patch comes from https://lore.kernel.org/all/20211207015505.16746-7-biao.huang@mediatek.com/

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
