ipa: rkisp1: awb: Remove bias from gain calculation
The red and blue gains are computed by dividing the green mean by the
red and blue means respectively. An offset of 1 is added to the dividers
to avoid divisions by zero. This introduces a bias in the gain values.
Fix it by clamping the divisors to a minimum of 1.0 instead of adding an
offset.
