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 v3:
- fix few clock register values
- collect mani a-b
Changes for v2:
- handle USB, GMAC clocks
- collect kever r-o-b tag
- simplify rd and wr conf API
