On dragonboard-410c (apq8016) with HFI_VERSION_1XX, the reported framerate is in unit of 1/65535 fps (for fine grained control). So the current reported supported frame intervals is wrong (max is 1/65535 fps), leading to encoding issues or format negotiation failures with gstreamer. Fix that by setting the framerate denominator to coherent value based on the the framerate factor. The factor is not always the same, e.g. with db820c (apq8096) HFI reports framerate in fps unit. So only apply that for HFI_VERSION_1XX.
