Ok, so I am able to reproduce this issue on a mx6qsabresd if I don't
pass the PCI gpio reset (like in nitrogen):

--- a/arch/arm/boot/dts/imx6qdl-sabresd.dtsi

        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_pcie>;
-       reset-gpio = <&gpio7 12 0>;
        status = "okay";
 };


Richard Zhu sent a fix for this, but it has not been applied yet:

With his patch applied the kernel can boot fine.
