Implement power scaling including a specific vpu2 and vpu3 calculation
for clock and bus bandwidth, which depends on the hardware
configuration, codec format, resolution and frame rate.

Handle the response sent by the firmware, when a source change is
detected. Read the subscribed parameter to get the changed values. Raise
the source change event to the client and update the instance sub-state.
Mark the last buffer from before the source change with the
V4L2_BUF_FLAG_LAST flag and return to the client.

Implement the vb2 ops for the buf queue. These are the different buffer
attributes:
BUF_ATTR_DEFERRED - buffer queued by the client but not submitted to
firmware.
BUF_ATTR_PENDING_RELEASE - buffers requested to be released from
the firmware.
BUF_ATTR_QUEUED - buffers submitted to the firmware.
BUF_ATTR_DEQUEUED - buffers received from the firmware.
BUF_ATTR_BUFFER_DONE - buffers sent back to vb2.

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.

Initialize the control handler by reading the platform specific firmware
capabilities. Capabilities are features, which are supported by a
specific platform (SOC). Each capability is defined with a min, max,
range and default value and a corresponding HFI. Implement s_ctrl and
g_volatile_ctrl ctrl ops.

Implement open, close and poll ops.
Open:
Configure the vb2 queue and v4l2 file handler. Allocate a video instance
and add the instance to core instance list.
Close:
Free the instance and remove it from core instance list.
Poll:
Wait for an event on vb2 src and vb2 dst queues.
