video: driver: add support to register custom handler.

Browse Source 
Need to increase debug timeout incase more debug logs were
enabled. This is to avoid sync cmd timeout.

module_param_cb supports to register custom set/get callbacks.
So using this feature to increase various timeout values,
incase more logs were enabled.
