msm: kgsl: Do a midframe sampling of power stats if enabled
Currently we sample power stats at the expiry of
cmdbatch. In cases where cmdbatch takes a long time
to finish the job, it delays power stats sampling,
in effect it delays DCVS decision for changing the
frequency. Do a midframe power stats sampling and
feed it to DCVS if it is enabled.
