2025-02-19drm/amd/display: Guard against setting dispclk low when activeNicholas Kazlauskas
[Why] We should never apply a minimum dispclk value while in prepare_bandwidth or while displays are active. This is always an optimization for when all displays are disabled. [How] Defer dispclk optimization until safe_to_lower = true and display_count reaches 0. Since 0 has a special value in this logic (ie. no dispclk required) we also need adjust the logic that clamps it for the actual request to PMFW.
