media: iris: Allocate and queue internal buffers for encoder video device
Add support for allocating and queuing internal buffers required by the
encoder. The sizes of these buffers are derived from hardware
specifications and are essential to meet the encoder's functional and
performance requirements.
These buffers are not exposed to userspace; they are allocated and
managed internally to ensure correct and efficient hardware operation.
