The PCIe driver covers different SOC which needing different clock
configs. Define them based on compatible.

v2:
- fix typo in mediatek,mt8192-pcie
v3:
- remove contains to match only if compatible is no fallback
  tested with series "Add driver nodes for MT8195 SoC" and mt7986
  pcie-nodes, dtbs_check is now clean
