RUBIK Pi 3 provides two camera connectors but ships without camera
modules, and each connector can be used with different sensors. Describe
only the board-level 3.3 V output rail in the base DTS and add optional,
per-connector overlays for Raspberry Pi Camera Module V2 IMX219 sensors.
CAM1 is connected to CCI1 and CSIPHY1, while CAM2 is connected to CCI0
and CSIPHY4. The overlays can be used independently or combined, and the
Makefile provides composed DTBs for both single-camera configurations and
the dual-IMX219 configuration.
Both dual-camera and single-camera configurations have been validated on
the RUBIK Pi 3.

Changes in v2:
- Keep the optional IMX219 sensors out of the base board DTS and add one
overlay per camera connector.
- Add composed DTBs for CAM1, CAM2, and dual-IMX219 configurations.
- Correct the power model: VCC3V3_OUTPUT is board-level, while each
PWR_EN controls the module-local sensor rails.
- Model the 24 MHz sensor input clock separately for each camera module.
- Describe CAMERA1_GPIO and CAMERA2_GPIO as privacy indicator LEDs and
associate each one with the corresponding sensor.
- Drop output-high and output-low from the GPIO pinctrl states.
- Rebase onto next-20260721.
