Surface Pro 9: Set correct front camera rotation

media: i2c: ov5693: add rotation control and apply 180° quirk for OVTI5693

The OVTI5693 module used in the Surface Pro 9 front camera is mounted upside‑down. libcamera ignores HFLIP/VFLIP and relies on V4L2_CID_CAMERA_SENSOR_ROTATION to determine sensor orientation, but the OV5693 driver did not expose this control.

This patch adds a rotation control to the driver and applies a 180° default for the OVTI5693 ACPI‑matched variant.

If I understand correctly, this would rotate all OV5693 senors, regardless of the actual device / mounting. Is there some way to get the mounting orientation from ACPI?

@djrscally maybe you know more?

I could remove the auto-rotation and leave the rotation control implemented if that's better?
Then user would need to issue v4l2-ctl --device to set rotation property.
It would be nice if this could be done automatically.
