[PATCH 11/22] drm/amd/display: enable phy-ssc reduction by default

[Zaeem Mohamed]

From: Roman Li <roman...@amd.com>

[Why]
Reduction of phy-ssc is needed to support DP2 high pixel clock on dcn35x/36.
There's a special flag to enable it in dmub hw params.

[How]
Set hbr3_phy_ssc to true for dcn35, dcn351 and dcn36.
