[ Upstream commit 95d620adb48f7728e67d82f56f756e8d451cf8d2 ] [Why] Currently mode validation is bypassed if remote sink exists. That leads to mode set issue when a BW bottle neck exists in the link path, e.g., a DP-to-HDMI converter that only supports HDMI 1.4. Any invalid mode passed to Linux user space will cause the modeset failure due to limitation of Linux user space implementation. [How] Mode validation is skipped only if in edid override. For real remote sink, clock limit check should be done for HDMI remote sink. Have HDMI related remote sink going through mode validation to elimiate modes which pixel clock exceeds BW limitation.
