media: hantro: Implement support for encoder commands
The V4L2 stateful encoder uAPI specification requires that drivers
support the ENCODER_CMD ioctl to allow draining of buffers. This
however was not implemented, and causes issues for some userspace
applications.
Implement support for the ENCODER_CMD ioctl using v4l2-mem2mem helpers.
This is entirely based on existing code found in the vicodec test
driver.
