Client expects all the buffers to be returned in certain scenarios
but driver does not return due to decode batching feature. Add
delayed_work functionality to queue batched buffers to video hardware
upon timeout, so that all the buffers will be returned to client.

Calculate DDR and LLCC bw simulteneously to avoid
redundant calculations. This reduces number of calculations
required by 50% and hence reduces cpu load.

Scaling capability are defined in Q16 format. Existing
capability indicates that the capability is 16 times i.e
output dimension can be scaled to 1/16th of input dimension.
As per specification, the achievable ratio is 8.

v4l2_ctrl_get_name may return NULL that leads to NULL

dereferencing if it is NULL.

is in flush. Return error if client queue buffer

due to release buffer reference event processing.
