[PATCH] media: ipu-bridge: Add upside-down sensor DMI quirk for Samsung Galaxy Book3 Pro

[Felipe Calliari]

The Samsung Galaxy Book3 Pro (960XFG) has the same problem as the
Galaxy Book3 Ultra (960XFH): its OV02C10 sensor is mounted upside-down,
but neither the SSDB nor the _PLD reports the 180 degree rotation, so
ipu_bridge_parse_rotation() assigns a "rotation" property of 0 to the
sensor fwnode and the image is rendered upside-down in userspace.

Add a DMI quirk entry for this laptop so that the sensor fwnode gets a
"rotation" property of 180 and userspace (e.g. libcamera) can
compensate.

The DMI strings (sys_vendor "SAMSUNG ELECTRONICS CO., LTD.",
product_name "960XFG") and the upside-down image come from a report
against the ov02c10 26 MHz clock series.
