[PATCH v3 2/4] venus: core: vote for video-mem path

[Mansur Alisha Shaik]

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")
