drm/amd/display: Factor in immediate flip support into DLG calculations
[Why]
We expect to be able to perform immediate flipping without having to
recalculate and update all the watermarks.
There are certain usecases today (1080p @ 90deg, 2160p @ 90deg) such
that we get a urgency value of 0 for frac_urg_bw_flip because we're
explicitly passing in a value of "false" for requiring immediate
flip support into the DLG calculation.
[How]
Always pass in true into the calculation. With this we get a correct
non-zero value for frac_urg_bw_flip.
