Revert "KGSL: Simple Governor: some styling changes, early returns instead of assigning a val and returning in the end of the function call and change the copyright/author from the middle of the file to the header."

This reverts commit 4f5a64d5875ef664e8826057418dca614e99930a.
msm: kgsl: Process all idle checks

Rather than ignore some categories of idle events,
bin the events with small timelines and process all
events with the GPU DCVS algorithm.

msm: kgsl: Bump up the GPU frequency for long batch processing

Compute workloads run without kernel interaction for long periods
of time.  If one is identified early, increase the frequency to
finish it as fast as possible, rather than waiting for the standard
algorithm to do so.
