media: iris: implement vb2 streaming ops
During the stream on operation, send HFI_CMD_START on the capture and
output planes to start processing on the respective planes.
During the stream off operation, send HFI_CMD_STOP to the firmware,
which is a synchronous command. After the response is received by the
firmware, the session is closed on the firmware.
Introduce different states for the instance and state transitions.
IRIS_INST_INIT - video instance is opened.
IRIS_INST_INPUT_STREAMING - stream on is completed on output plane.
IRIS_INST_OUTPUT_STREAMING - stream on is completed on capture plane.
IRIS_INST_STREAMING - stream on is completed on both output and capture
planes.
IRIS_INST_DEINIT - video instance is closed.
IRIS_INST_ERROR - error state.
