ath12k - HTT timeout error with NCM86

[Dieter Knueppel]

Minor update:

I just figured out, that even the physical machine with std. Ubuntu
24.04 server (before the VM gets started and PCI device vanishes on PM)
reports: "Unknown hardware version found for WCN7850: 0xf"

Hence the earlier question, whether "MSI HERALD-BE" or "Gigabyte
GC-WIFI7" is supported, seems still to be valid.
