ipa: rkisp1: Port to the new AEGC controls
The newly introduced controls to drive the AEGC algorithm allow
controlling the computation of the exposure time and analogue gain
separately.
Augument the RkISP1 AEGC implementation to handle the exposure and gain
controls separately using the new controls.
