[Impact]
*** this issue happen with secure boot on and issue gone when secure boot is off***

After the BIOS loading screen, a yellow screen pops up in an instant (< 1 second) and then disappears. Attached a demo video.

[Fix]
do what intel_color_commit() does to make sure the bottom color state
matches whatever out hardware readout produced.
Ref. https://patchwork.freedesktop.org/patch/456170/?series=95171&rev=1

[Test]
1. Power on the system
2. Check if any unusual screen shows before and after the system loading screen.
3. No unusual screen shows before and after the system loading screen

[Regression Potential]
Medium, maintainer still not totally sure what should do about color management
features here in general.
