Subject: ipa: ipu3: Add support for IPU3 AEC/AGC algorithm

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.
