ipa: rkisp1: ccm/lsc: Fix CCM/LSC based on manual color temperature
In RkISP1Awb::process(), the color temperature in the active state is
updated every time new statistics are available. The CCM/LSC algorithms
use that value in prepare() to update the CCM/LSC. This is not correct
if the color temperature was specified manually and leads to visible
flicker even when AwbEnable is set to false.
To fix that, track the auto and manual color temperature separately in
active state. In Awb::prepare() the current frame context is updated
with the corresponding value from active state. Change the algorithms to
fetch the color temperature from the frame context instead of the active
state in prepare().
Fixes: 02308809548d ("ipa: rkisp1: awb: Implement ColourTemperature control")
