Improve the condition used to determine when input internal buffers need
to be reconfigured during streamon on the capture port. Previously, the
check relied on the INPUT_PAUSE sub-state, which was also being set
during seek operations. This led to input buffers being queued multiple
times to the firmware, causing session errors due to duplicate buffer
submissions.
This change introduces a more accurate check using the FIRST_IPSC and
DRC sub-states to ensure that input buffer reconfiguration is triggered
only during resolution change scenarios, such as streamoff/on on the
capture port. This avoids duplicate buffer queuing during seek
operations.

Implement support for queuing and dequeuing input and output buffers
for the encoder video device using the appropriate V4L2 buffer
management ioctls.
This enables userspace applications to manage streaming buffers
required for encoding operations.

Add support for V4L2 streaming operations on the encoder video device.
During stream-on, configure mandatory properties on the respective
planes and notify the firmware to initiate an encode session.
