[PATCH 2/3] media: hantro: Add support for RK356x JPEG encoder

[Nicolas Frattaroli <frattaroli.nicolas@gmail.com>]

The RK3566 and RK3568 SoCs come with a small Hantro instance which
is solely dedicated to encoding JPEG. This patch adds the necessary
structs to the Hantro driver to allow it to function.

Tested with the following GStreamer command:

gst-launch-1.0 videotestsrc ! v4l2jpegenc ! matroskamux ! \
               filesink location=foo.mkv
