Pedro confirmed that the Wifi card can be detected now with these
patches applied.

Just submitted the patches to the list.

Upgrading to a 5.4.16 imx6sx.dtsi fixed the issue and the reason is
the following hunk:

- reg = <0x08ffc000 0x4000>; /* DBI */
+ reg = <0x08ffc000 0x04000>, <0x08f00000 0x80000>;

The old imx6sx.dtsi only had the dbi entry and no cfg.

The version in mainline has the cfg entry, which is needed for the imx
PCI U-Boot DM driver.

Thanks
