drm/amd/display: do not force UCLK DPM to stay at highest state during display off in DCN2
[Why]
Add optimization to allow pstate change support when all displays
are off in DCN2.
[How]
Add clk_mgr_helper_get_active_plane_cnt() to sum plane_count for all
valid stream_status[]. If plane_count is 0, then there are no active
or virtual streams present. Use plane_count == 0 as extra condition to
enable p_state_change_support in dcn2_update_clocks().
