[PATCH v3] dt-bindings: PCI: mediatek-gen3: Add support for MT8188 and MT8195

[Jianjun Wang]

MT8188 and MT8195 are ARM platform SoCs with the same PCIe IP as MT8192.

Also add new clock name "peri_mem" since the MT8188 and MT8195 use clock
"peri_mem" instead of "top_133m".

Changes in v3:
Use enum property to add the new clock name.

Changes in v2:
Merge two patches into one.
