[PATCH] media: i2c: imx258: Parse and register properties

[Robert Mader <robert.mader@collabora.com>]

Analogous to e.g. the imx219. This enables propagating
V4L2_CID_CAMERA_SENSOR_ROTATION values so that libcamera
can detect the correct rotation from the device tree
and propagate it further to e.g. Pipewire.
