[0/4] Enable JPEG encoding on rk3588

Only the JPEG encoder is available for now, although there are patches
for the undocumented VP8 encoder floating around[0].

This has been tested on a rock-5b, resulting in four /dev/video*
encoders.  The userspace program I’ve been using to test them is
Onix[1], using the jpeg-encoder example, it will pick one of these four
at random (but displays the one it picked):
% ffmpeg -i <input image> -pix_fmt yuvj420p temp.yuv
% jpeg-encoder temp.yuv <width> <height> NV12 <quality> output.jpeg
