Add StarFighter 4K resolution quirk

[Sean-StarLabs]

Add a downstream DRM EDID patch for the StarFighter 4K panel.

The patch keeps all advertised modes available, but on Star Labs StarFighter eDP panels with a 3840x2400 mode present, it marks 1920x1200 as preferred. If 1920x1200 is not advertised, it falls back to 2560x1600.

Local validation:

• git diff --check
• checkpatch.pl --strict --no-tree --ignore CAMELCASE on the carried patch
• git apply --check against upstream v6.18.40

Not runtime-tested on Qubes hardware yet.

series.conf is not used anymore (I will remove it later, to not confuse anymore), now patches are listed directly in kernel.spec.in.

But then, unfortunately it doesn't work. In fact, /sys/class/drm/card0-eDP-1/modes lists only the native mode (twice, for some reason). But Xorg lists all of them. Maybe changing the default requires EDID change, or Xorg patch?
