It is possible that BDF name with board-id+chip-id+variant
combination is not found in the board-2.bin. Such cases can
cause wlan probe to fail and completely break wifi. In such
case there can be an optional property to define a default
BDF name to search for in the board-2.bin file when none of
the combinations (board-id,chip-id,variant) match.
To address the above concern provide an optional proptery:
qcom,ath10k-default-bdf
