drm/amd/display: Keep VBios pixel rate div setting until next mode set

2024-06-05T15:04:50+00:00

[why] Vbios & Driver have difference pixel rate div policy. When enabling fast boot & performing blank & unblank w/o timing setting, pixel clock & pixel rate dividor are not match. It would cause too high pixel reate and eDP would be black screen. [How] We would keep pixel rate div setting by Vbios until next timing setting.
