drm/amd/display: Add DSC delay factor workaround
[Why]
Certain 4K high refresh rate modes requiring DSC are exhibiting top
of screen underflow corruption. Increasing the DSC delay by a factor
of 6 percent stops the underflow for most use cases.
[How]
Multiply DSC delay requirement in DML by a factor.
Add debug option to make this DSC delay factor configurable.
