[Intel-gfx] [PATCH 2/2] drm/edid: Remove defunct EDID_QUIRK_FIRST_DETAILED_PREFERRED

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Looks like EDID_QUIRK_FIRST_DETAILED_PREFERRED never did anything.
Its counterpart in f86EdidModes.c is properly hooked up but somehow
that functionality was lost when it was copied into the kernel.

Assuming that another preferred mode didn't sneak in somehow
(is that even possible?) this should now be fully covered by the
generic fallback that marks the first probed mode as preferred.
So let's just remove the quirk.

I tried to double check the known cases:
* Proview AY765C
  https://bugs.freedesktop.org/show_bug.cgi?id=15160 seems OK
* Unknown Acer
  https://bugzilla.redhat.com/show_bug.cgi?id=284231 (got the
  reference from xf86EdidModes.c), no access
* Philips 107p5 CRT
  "Reported on xorg@ with pastebin", didn't find the mail(s)
* Peacock Ergovision 19 (only in xf86EdidModes.c)
  https://bugzilla.redhat.com/show_bug.cgi?id=492359 seems OK
