[PATCH v2] media: ipu-bridge: Add upside-down quirk for Surface Pro 11

[PATCH v2] media: ipu-bridge: Add upside-down quirk for Surface Pro 11

[Sergey Lebedev]

The Microsoft Surface Pro for Business 11th Edition with Intel mounts
its OV13858 rear sensor rotated 180 degrees, but reports a rotation of
0 in its SSDB and has no matching _PLD, so without a DMI quirk the
image is presented upside down.

Add a DMI quirk entry for this model so that a rotation of 180 degrees
is reported for its OVTID858 sensor.

Tested on the affected machine: camera_sensor_rotation reads 180 and
libcamera reports Rotation = 180. Confirmed independently on a second
machine of the same model, where GNOME Snapshot and Firefox present
the image the right way up once the quirk is applied; qcam, which
talks to libcamera directly, does not.

Changes in v2:
 - shortened the commit message, per Sakari's review of v1
 - moved the entry into vendor order, before the Samsung entries
 - added German Pablo Lindo's Tested-by

v1: https://lore.kernel.org/linux-media/20260913153526.80287-1-lsa.uz@pm.me/

The quirk only has an effect once OVTID858 is a recognised sensor, which
  https://lore.kernel.org/linux-media/20260913142034.5632-1-lsa.uz@pm.me/
adds; this patch applies to media/next independently of it.
