Currently, only the single-PHY architecture is supported in ath12k. The split-PHY QCN9274 requires different AMSS firmware binary "amss_dualmac.bin". Hence, add support to read board id from OTP. Based on board id decide whether single-mac / dual-mac firmware needs to be downloaded to the target. Also, update HW param max_radios to support split-PHY in QCN9274. Also, add new Firmware IE for firmware_N.bin "ATH11K_FW_IE_AMSS_DUALMAC_IMAGE" to support dualmac QCN9274.
