sc8280xp is the SoC found in the Lenovo X13s. This series adds support to
bring up the CSIPHY, CSID, VFE/RDI interfaces.

A number of precursor patches make this series smaller overall than
previous series.

sc8280xp provides

- 4 x VFE, 4 RDI per VFE
- 4 x VFE Lite, 4 RDI per VFE
- 4 x CSID
- 4 x CSID Lite
- 4 x CSI PHY

I've taken the yaml from a dtsi series and included it here since 1) I sent
the yaml to the wrong person and 2) it already has RB from Krzysztof.

Requires CAMCC for sc8280xp which applies to qcom/clk-for-6.7:

b4 shazam 20231026105345.3376-1-bryan.odonoghue@linaro.org

Requires the named power-domain patches which apply to media-tree/* :

To use the camera on x13s with say Google Hangouts or Microsoft Teams you
will need to

1. Run Firefox
2. Update about:config to enable pipewire
3. Use this WIP version of libcamera
   https://gitlab.freedesktop.org/camera/libcamera-softisp
