[PATCH v4 1/3] dt-bindings: PCI: mediatek-gen3: Support mt8195

[Tinghan Shen]

From: Jianjun Wang <jianjun.wang@xxxxxxxxxxxx>

In order to support mt8195 pcie node, update the yaml to support new
properties of iommu and power-domain, and update the reset-names
property to allow only one 'mac' name.
