Subject: [PATCH] wifi: ath12k: Fetch regdb.bin file from board-2.bin
Currently, ath12k_core_fetch_regdb() finds regdb.bin file through
board id's but in board-2.bin file regdb.bin file is present with
default board id because of which regdb.bin is not fetched.
Add support to fetch regdb.bin file from board-2.bin through
default board id.
