Currently we are voting for venus0-ebi path during buffer processing
with an average bandwidth of all the instances and unvoting during
session release.
While video streaming when we try to do XO-SD using the command
"echo mem > /sys/power/state command" , device is not entering
to suspend state and from interconnect summary seeing votes for venus0-ebi
Corrected this by voting for venus0-ebi path in venus_runtime_resume
and unvote during venus_runtime_suspend.

This also shows that the arguments to icc_set_bw() we're backwards? Can
that be fixed in another patch instead of putting it in this one?
