ath79: fix ath10k caldata extraction on some D-Link DIR-842 C3 devices
According to forum threads [0][1] and a report on IRC by Doc-Saintly
some of those boards have calibration data in a different place. Only
one alternative location is known.
Without proper board calibration data (board.bin having all 0xff bytes)
ath10k firmware still tries to load but crashes on startup with a
confusing error message.
If you're applying this patch manually on your device do not forget to
remove /lib/firmware/ath10k/pre-cal-pci-0000:00:00.0.bin and reboot to
force caldata re-extraction.
