Bug description:
  [Impact]
  Some new laptop display set EDID continuous freq bit 1.
  Then Xorg only uses the timing modes defined in EDID, no other modes are 
shown on Xorg.

  Upstream Bug:
  https://gitlab.freedesktop.org/drm/intel/-/issues/313

  Fix of Xorg in merge request:
  https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/421

  
https://cgit.freedesktop.org/xorg/xserver/commit/?id=6a79a737e2c0bc730ee693b4ea4a1530c108be4e

  this is required to support new laptop models which use such panels

  [Test case]
  Test that a proper list of modes is shown with a panel that uses the new EDID.

  [Regression potential]
  The patch retains the previous code path for setting modes on GTF-able 
monitors, and only adds support for non-GTF monitors. So in that sense there 
shouldn't be any regression potential, this has been reviewed by an upstream 
expert.
