Currently video driver is 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().

Fixes: 7482a983d ("media: venus: redesign clocks and pm domains control")

In fact all changes in this series are related to interconnect. The
interconnect calls are moved to venus_runtime_suspend/resume by commit
[1], that's why I think the Fixes: tag for all patches in this series
should be [1].

[1] 07f8f22a33a9e ("media: venus: core: remove CNOC voting while device
suspend")
