ipa: rkisp1: Add manual color gains

Browse source 
Add support for manually controlling the color gains on the rkisp1 IPA.
To that end, add and plumb the AwbEnable and ColourGains controls. As
per-frame controls aren't supported yet in the rkisp1 IPA, simply apply
and perform checks on the controls immediately.
