From: Vikash Garodia <quic_vgarodia@xxxxxxxxxxx>
Implement all iris v4l2 ioctls ops supported by decoder.
Add state checks to ensure ioctl are allowed in valid
instance state only. Codec format can be changed by client
during s_fmt. Update the v4l2 control values according
to the updated codec format.
