msm: vidc: ensure venus is in power on before scaling clocks
It is to be ensured that venus is in power on state before scaling
clocks. When venus goes to power collapse, a resume can happen
either when driver writes some command to the command queue or any
response comes from firmware. So when client requests a particular
perf_level, venus is not resumed and scale clocks is called.
