This series support PCIe host controller support on rockchip rk3399 platform.
It is based on previous version[1] changes.
Works well on rk3399 boards like rock960, nanopc-t4 and roc-kr3399-pc-mezzanine board as Gen1 configurable host with M.2 SSD.
Changes for v2: - handle USB, GMAC clocks - collect kever r-o-b tag - simplify rd and wr conf API
