For some encoder cases, user driver need to get encoded message for each frame. So add support read-only(Ro) request for capture queue. Ro request mean that user driver just can get ext ctrls, set ext ctrls is not not allowed. Ro Request also can be used in output queue. There is not upstream driver to use this feature at now, but we are developing internal driver to use it. If it is ready, we will try to upstream vdec/venc driver based on this feature.
