Currently ath12k only downloads the same regdb.bin file for all WCN7850
chips, actually ath12k needs to distinguish all different WCN7850 chips.

This is to re-use the string type which includes bus, chip id, board id,
vendor, device, subsystem-vendor, subsystem-device and variant for
WCN7850 to distinguish different regdb in board-2.bin.

ath12k will first load board-2.bin and search in it for the regdb data
with the above parameters. If matched with one regdb data, download it
to firmware. And if not, download regdb.bin instead.

Add enum value ATH12K_BD_IE_REGDB and enum type ath12k_bd_ie_regdb_type
to distinguish regdb data and board data since they are in the same file
board-2.bin.
