media: venus: core: vote for video-mem path
[ Upstream commit 9e8efdb5787986cc0d0134925cf5c4f001bb3f2e ]
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().
