drm/sysfb: Use preferred panel size for panel orientation quirks

Browse source

Sysfb drivers currently use the given display mode for looking up the
panel orientation. But the look-up table stores the native geometry of
the panels, so the lookup fails if the current mode sizes differs.

Get the panel's native geometry with drm_edid_detect_panel_size() from
the EDID and use it for looking up the panel orientation.

v2:
- ofdrm: validate EDID header before using it (Sashiko)
