2021-06-08	ipa: ipu3: Calculate line duration from IPACameraSensorInfo	Umang Jain
	Squash \todo by calculating line duration from IPACameraSensorInfo, now passed in, to IPU3Agc::initialise(). Since line duration is now calculated from real values, store it as a private member in IPU3Agc class. As a further step, replace the associated global constant, kMaxExposureTime, with a private IPU3Agc class member as well, and assign its value correspondingly in IPU3Agc::initialise(), similar to previous precedence.

2021-04-22	ipa: ipu3: Add support for IPU3 AEC/AGC algorithm	Jean-Michel Hautbois
	Implement basic auto-exposure (AE) and auto-gain (AG) correction functions. The functions computeTargetExposure() and computeGain() are adapted from the Raspberry Pi AGC implementation to suit the IPU3 structures, and filtering is added to reduce visible stepsize when there are large exposure changes.
