@desperex Hello, actually I fixed issue. I need additional testing for provide a path to armbian branch 

So I see you found the same solution, but the other way around=) 

 

The simplest patch would be another overlay, so you can optionally switch this on if you have issues with pcie device:

/linux-source-rockchip64/arch/arm64/boot/dts/rockchip/overlay/rockchip-rk3399-bus-scan-delay.dts

/dts-v1/;
/plugin/;

/ {
    compatible = "rockchip,rk3399";
    fragment@0 {
        target = <&pcie0>;
        __overlay__ {
            bus-scan-delay-ms = <1000>;
        };
    };
};

Yes almost 
In your solution mess in rk3399-rock-pi-4.dtsi still exist, and I think it's not good for system stable work. 
Also I try different variants with/without vpcie0v9-supply, vpcie1v8-supply but I got different errors or not soft reboot with this two parameters...

So yes, we were digging in the right direction )))
