[SP14] Add HAL to set warning quota to tehtering offload hardware
With current setDataLimit API, tethering offload hardware will
stop offload and trigger callback when the given limit bytes is
reached.
However, for data usage warning to work, an API that allows
tethering offload hardware to report event without stopping
offload hardware is needed.
