Copy hw settings to adjusted mode

Examining things more closely I noticed this as the first difference..

Bad:
[drm:intel_dump_pipe_config] requested mode:
[drm:drm_mode_debug_printmodeline] Modeline 0:"" 0 108000 1280 1328 1440 1688
1024 1025 1028 1066 0x0 0x5
[drm:intel_dump_pipe_config] adjusted mode:
[drm:drm_mode_debug_printmodeline] Modeline 0:"" 0 0 0 0 0 0 0 0 0 0 0x0 0x5

Good:
[drm:intel_dump_pipe_config] requested mode:
[drm:drm_mode_debug_printmodeline] Modeline 0:"1280x1024" 60 108000 1280 1328
