imho they are shared across SoCs rk3568 and rk3588, but have only seen rk3568 implementation yet.
PCIe driver currently supports these 2 Soc (different offsets in the Phy-GRF), but can only test rk3568.

pipe-grf seems only be used for rk35688 (offset used in probe is defined for this SoC), which i cannot test.

so i have left them SoC independed.
