[PATCH v1 0/2] RK3588 PCIe3 support

Hi,

This adds PCIe v3 support for RK3588. The series has been tested with
Rockchip RK3588 EVB1 and a PCIe wlan card, I will also test Rock 5B
next week. The series depends on the PCIe v2 series [0].

Note, that the PCIe3 PHY driver is currently missing bifurcation
support for RK3588. Thus after this series only PCIe3x4 is usable
(in aggregated x4 mode) without adding support for the PHY's
"rockchip,pcie30-phymode" DT property, which allows configuring
how the lanes are distributed. Apparently this seems to be the
most common configuration. Both EVB1 and Rock 5B use it, so I
cannot test anything else anyways.
