Subject[RESEND v2 2/4] venus: core: vote for video-mem path
Date
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().

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

Resending by adding () for functions to know it as function.
