Add driver for Rockchip PCIe root complex found in RK3399 SOC.
Unfortunately, there are some limitations:
- memory aperture of his controller is only 16MiB, so it is nearly
  unusable for graphic cards
- every attempt to generate type 1 config cycle always causes trap.
  These config cycles are disabled now and we don't support cards
  with PCIe switch.
- in some cases, attempt to do config cycle to (probably) not-yet ready
  card also causes trap. This cannot be detected at runtime, but it seems
  like very rare issue.
