drm/amd/display: properly configure DCFCLK when enable/disable Freesync

Browse source

[Why]
Bandwidth validation is using Freesync parameters
from previous Freesync state.
Bandwidth validation ignores DCFCLK calculated
after Freesync parameters are configured

[How]
Set Freesync bandwidth parameters to its default
state before running bandwidth validation.
Take DCFCLK calculated after Freesync bandwidth
parameters are assigned and bandwidth is
recalculated.
