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.
