wifi: rtw89: fw: add version field to BB MCU firmware element
8922AE has more than one hardware version, and they use different BB MCU
firmware, so occupy a byte from element priv[] to annotate version. Since
there are more than one firmware and only matched version is adopted,
return 1 to ignore not matched firmware.
