<title>Revert "drm/amd/display: Fix sending VSC (+ colorimetry) packets for DP/eDP displays without PSR"</title>

This causes flicker on a bunch of eDP panels. The info_packet code
also caused regressions on other OSes that we haven't' seen on Linux
yet, but that is likely due to the fact that we haven't had a chance
to test those environments on Linux.

We'll need to revisit this.

This reverts commit 202260f64519e591b5cd99626e441b6559f571a3.

[WHY]
The original coasting vtotal is 2 bytes, and it need to
be amended to 4 bytes because low hz case.

[HOW]
Amend coasting vtotal from 2 bytes to 4 bytes.

<id>14d68acfd04b39f34eea7bea65dda652e6db5bf6</id>
<content type='text'>
[Why]
Nanosec stats can overflow on long running systems potentially causing
statistic logging issues.

[How]
Use 64bit types for nanosec stats to ensure no overflow.

<title>drm/amd/display: Replay + IPS + ABM in Full Screen VPB</title>

<id>f980579c29a6df2d30b44af958992be07baa0fcc</id>
<content type='text'>
[Why]
Because ABM will wait VStart to start getting histogram data,
 it will cause we can't enter IPS while full screnn video playing.

[How]
Modify the panel refresh rate to the maximun multiple of current
 refresh rate.
