[PATCH v1 11/11] ipa: rkisp1: awb: Apply gains based on default colour temperature on start

[Stefan Klug]

The colour gains are initialized with a default value of 1. Improve that
by querying the auto white balance algorithm for the gains for a default
colour temperature. This is still not based on measurements, but it is
still better than the current implementation. If the algorithm doesn't
implement mapping from colour temperature to gains, it will internally
fallback to 1.0.
