Enhance EDID quirks to allow forcing a mode

[Dylan Semler]

The idea is setup a new quirk list with width, height, and refresh rates for
each monitor that needs this quirk.  If a monitor is attached that matches one
in this list, the full modeline is calculated with drm_gtf_mode, the
DRM_MODE_TYPE_PREFERRED bit is set, and the new mode is added to the connector.

The patch also creates a new quirk bit:  EDID_QUIRK_FORCE_MODE.  This bit needs
to be set for the new quirk list discribed above to be checked.

The first patch enhances the quirk logic as described above.  The second one
adds my new monitor to the quirk lists.
