rework mtk pcie-gen3 bindings and support mt7986

From: Frank Wunderlich <[email protected]>

This Series prepares support for mt7986 PCIe which is basicly gen3 PCIe but with slightly differnt clock configuration.

To make differences better to read i split the exiting bindings which has already different settings with a compatible switch and then add a new one for mt7986.

v2:
- fixed typo in part 1 (SoC based config)
- squashed part2+3 (compatible and clock config for mt7986)

v3:
- fixed problem with fallback-compatible not compatible to main

Frank Wunderlich (2):
dt-bindings: PCI: mediatek-gen3: add SoC based clock config
dt-bindings: PCI: mediatek-gen3: add support for mt7986
