Enable the main RGB sensor on the Lenovo x13s a five megapixel 2 lane DPHY
MIPI sensor connected to cisphy0.

With the pm8008 patches recently applied to the x13s dtsi we can now also
enable the RGB sensor. Once done we have all upstream support necessary for
the RGB sensor on x13s.

The Lenovo x13s has a five megapixel ov5675 sensor as well as a one
megpixel ov9734 B+W NOIR sensor for low-light face detection login.

This patch enables the RGB sensor.

A gpio exists in the upstream dts to indicate camera activity which
currently we don't tie to CAMSS activity yet.

Running

- A Linux distro which ships libcamera > 0.3.0
- Firefox nightly
- Setting Firefox about:config:media.webrtc.capture.allow-pipewire = true

It should then be possible to use the on-board MIPI camera for Zoom,
Hangouts etc.

Changes in v2:
- Drops useless assigned-clocks entry 
- Link to v1: https://lore.kernel.org/r/20240801-b4-linux-next-24-07-31-camss-sc8280xp-lenovo-rgb-v2-v1-1-30622c6a0c48@linaro.org

Changes in v3:
- Incorporate Vlad's review
- Add Vlad's RB
