r355755: 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. r358807: Add the missing brackets to the logical expression.
