[PATCH v3 0/2] rework mtk pcie-gen3 bindings and support mt7986

[Frank Wunderlich]

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
