staging: vchiq_arm: get rid of global device structure
Get rid of the global g_dev structure.
This is part of an effort to address TODO item "Get rid of all non
essential global structures and create a proper per device structure"
I chose to pass the vchiq_instance around instead of the device
reference because in order to get rid of the 'vchiq_states' global array
in the future, we will need another way to access the vchiq_state in the
'handle_to_service' function. Therefore, we will need to pass the
vchiq_instance to it (or the vchiq_state), and also pass it to functions
higher up in the caller chain, such as 'vchiq_bulk_transmit' and friends
which are used in the bcm2835-audio consumer.
