forgectrl: VPU JPEG encode for the camera stream - 7.9 fps

Browse Source 
Demosaic the superpixels straight to planar YUV420 and encode on the CODA960 (mainline coda V4L2 mem2mem, node found by personality); libjpeg stays as the automatic fallback and the snapshot path. All camera paths now demosaic from a cached bounce copy of the frame: the V4L2 MMAP capture buffers are uncached, and reading them in-place costs ~340 ms/frame vs 43 ms memcpy + 75 ms cached convert. Per-frame stats logged every 100 frames; /cam/status reports the encoder.
