After thinking more about this I agree, we want to have just one board-2.bin file for WCN3990 as it makes easier to share board files across all variants.

Different Qualcomm platforms using WCN3990 WiFI chip use SoC-specific firmware versions with different features. For example firmware for SDM845 doesn't use single-chan-info-per-channel feature, while firmware for QRB2210 / QRB4210 requires that feature. Allow board DT files to override the subdir of the fw dir used to lookup the firmware-N.bin file decribing corresponding WiFi firmware. For example: - ath10k/WCN3990/hw1.0/wlanmdsp.mbn, ath10k/WCN3990/hw1.0/firmware-5.bin: main firmware files, used by default - ath10k/WCN3990/hw1.0/qcm2290/wlanmdsp.mbn, ath10k/WCN3990/hw1.0/qcm2290/firmware-5.bin: SoC specific firmware with different signature and feature bits Note, while board files lookup uses the same function and thus it is possible to provide board-specific board-2.bin files, this is not required in 99% of cases as board-2.bin already contains a way to provide board-specific data with finer granularity than DT overrides.
