staging: vchiq_arm: add reference to vchiq device in vchiq_state

Add a reference to the vchiq device in the vchiq_state structure. This
allows the device structure to be passed around, which will be useful in
order to get rid of the global g_dev structure. This change will also
make it possible to use standard kernel logging macros instead of the
custom ones.
