staging: vchiq_arm: pass vchiq instance to service callbacks
In order to remove the 'vchiq_states' global array, we need to pass the
vchiq_instance reference to the 'handle_to_service' function, as well as
to all functions that call 'handle_to_service'. This will allow
accessing the vchiq state through the vchiq instance instead of through
the global array.
'handle_to_service' is called by 'service_callback'. Therefore, pass the
vchiq instance reference to 'service_callback'. This also requires
adding the vchiq instance reference to the service callbacks prototype,
and update all other callbacks accordingly.
