Currently ath11k only download the same regdb.bin file for all WCN6855
chips, actually ath11k needs to distinguish all different WCN6855 chips.

This is to re-use the string type which include bus, chip id, board id,
vendor, device, subsystem-vendor, subsystem-device and variant for
WCN6855 to distinguish different regdb in board-2.bin.

ath11k will first load board-2.bin and search in it for the regdb data
with the above parameters, if matched one regdb data, then download it
to firmware, if not matched any one, then ath11k will download the file
regdb.bin to firmware.

Add enum value ATH11K_BD_IE_REGDB and enum type ath11k_bd_ie_regdb_type
to distinguish regdb data and board data since they are in the same file
board-2.bin.

This only take effect for WCN6855 which supports regdb in hardware parameters.
