staging: vchiq_arm: pass vchiq instance to 'handle_to_service'
In order to remove the 'vchiq_states' global array, we need to pass the
vchiq_instance reference to the 'handle_to_service' function. This will
allow accessing the vchiq state through the vchiq instance instead of
through the global array.
