ipa: ipu3: Calculate frame duration from minimum VBLANK value
Frame duration is hard-coded for CTS as per [1]. Ideally, to accurately calculate the frame duration, it needs the VBLANK value from every frame's exposure. However, this particular bit is yet to be implemented in IPAIPU3. Meanwhile, we can at least head in the right direction by not hard coding the value, instead using the default VBLANK value as reported by the sensor. Update the existing \todo, to use the derived VBLANK value as and when it's available from each frame exposure.
