drm: hisilicon: Filter out unsupport modes and reorder modes according to testingworking-hdmi-test-0908-01
1. Filter out DRM_MODE_FLAG_INTERLACE modes.
2. Filter out unsupport pixel clock modes.
3. Support these modes as high priority if exist in EDID:
1920x1200 16:10 Monitor
1920x1080 16:9 TV
1680x1050 16:10 Monitor
1280x1024 5:4 Monitor
1280x720 16:9 TV
800x600 4:3 TV
