kgsl: gpu: part 1: increased gpu bandwidth and bumped up 3D GPU frequency
kgsl: gpu: part 2: adding in 3D scaling control
kgsl: gpu: part 3: added files and defconfigs
Fix up
kgsl: gpu: update max power levels
kgsl: gpu: part 4: disable 2D sysfs interface for now since we aren't over clocking it
kgsl: gpu: fix 3D frequency scaling

Existing logic had redundant code and wasn't exactly
efficient in scaling the governor.  Removed unnecessary
logic and cleaned it up a bit.
