[ Upstream commit 24f587572acf7509127dbdfcbf1b681ef84eeba0 ]

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.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
