msm: vidc: Introduce ETB flag for Enc Superframe handling 



Driver will internally produce subframe flag for all ETB of
a Superframe to firmware (except last ETB). Firmware will
propagate subframe flag to FBD. Driver client will receive
multiple FBDs with subframe flag for single Superframe ETB
(except last FBD). This subframe flag indicates that more
FBD expected for same input.
