drm/amd/display: Add below the range support for FreeSync
[Why]
When the flip-rate is below the minimum supported variable refresh rate
range for the monitor the front porch wait will timeout and be
frequently misaligned resulting in stuttering and/or flickering.
The FreeSync module can still maintain a smooth and flicker free
image when the monitor has a refresh rate range such that the maximum
refresh > 2 * minimum refresh by utilizing low framerate compensation,
"below the range".
[How]
Hook up the pre-flip and post-flip handlers from the FreeSync module.
These adjust the minimum/maximum vrr range to duplicate frames
when appropriate by tracking flip timestamps.
