Add ESP32-S3 CAM controller driver implementing the NuttX imgdata
interface. Supports 8-bit DVP camera input with DMA-based frame
capture, VSYNC interrupt handling, and PSRAM frame buffer allocation.
The driver is sensor-agnostic: resolution and pixel format are
negotiated at runtime through the V4L2 pipeline. XCLK output
(24 MHz) is started during initialization for sensor communication.
