media: iris: Set platform capabilities to firmware for encoder video device
Initialize and configure platform-specific capabilities for the encoder
in the firmware during stream-on, to tailor encoding behavior to the
current session's requirements. Some of these capabilities can also be
updated dynamically when V4L2 controls are modified by the client after
stream-on.
