This is still likely the problem. u-boot (or the u-boot) environment
needs to pick up the right DTB and it dosen't appear to be.

you can check the dtb on disk by using

dtc -I dtb -O dts /boot/dtb/starfive/jh7110-starfive-visionfive-2-v1.2a.dtb

pcie@940000000 has the xhci attached to it.

Also, I've just added ofctl support and if you have it you can check the
DTB that was used...
