at first thank for all the great work. Currently i don't have much time
to give a feedback for everything :-(

Tbh this TODO is not finished yet. There are still global structures.
Please look at variables starting with g_* in vchiq_arm.c and
vchiq_connected.c

Unfortunately i cannot tell which of them are easy to move into the
device structure.
