[REGRESSION] Update of linux-firmware breaks wifi on Thinkpad T14

[Christian Heusel]

Hello Kalle,

the commit 82318c96 ("ath12k: WCN7850 hw2.0: update board-2.bin") in the
linux firmware repository apparently breaks card recognition in Thinkpad
T14 laptops with the following journal entries:

    Sep 10 12:34:01 gdb-arch-t14-5 kernel: ath12k_pci 0000:02:00.0: failed to fetch board data for bus=pci,vendor=17cb,device=1107,subsystem-vendor=17aa,subsystem>
    Sep 10 12:34:01 gdb-arch-t14-5 kernel: ath12k_pci 0000:02:00.0: failed to fetch board.bin from WCN7850/hw2.0
    Sep 10 12:34:01 gdb-arch-t14-5 kernel: ath12k_pci 0000:02:00.0: qmi failed to load bdf:
    Sep 10 12:34:01 gdb-arch-t14-5 kernel: ath12k_pci 0000:02:00.0: qmi failed to load board data file:-2

Is there any more information you would need to debug this issue or does
the above already tell you enough?

This issue was discovered by Arch Linux Forum user "Mezzy12" with
debugging help from user "loqs" and me.

Regards,
Chris
