The Dell XPS 16 DA16260 ships in more than one panel variant. The existing
quirk entry only matches the LG Display panel with DPCD sink OUI 00:22:b9.
Another variant of the same laptop (subsystem 1028:0dba) uses an LG Display
0x07C5 panel with sink OUI 00:aa:01, which is not matched, so eDP Panel
Replay stays enabled and the panel hits a persistent PANEL-REPLAY Link CRC
error, dropping the internal display to ~5 fps.
Add a quirk entry for OUI 00:aa:01 so this variant also gets eDP Panel
Replay disabled. Confirmed xe.enable_panel_replay=0 resolves the issue.

as a quirk")
