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.

msm: kgsl: we don't need this routine anymore. We save CPU cycles not going through this small, now deleted, piece of code.

msm: kgsl: use kgsl_mmu_device_setstate() if the GPU is already idle

Use the default setstate function, which directly reprograms the IOMMU,
to change IOMMU pagetables or flush the TLB if the GPU is already idle.
This condition often occurs when the GPU is being powered down. In this
case it is desirable to avoid the overhead of issuing commands, waiting
for idle and firing events that results from using the GPU
command stream to reprogram the IOMMU.

kgsl: add a new governor algorithm. Ditch the older Simple Governor to make place for Interactive. This name is chosen just to differentiate from the others, but it doesn't behave like the CPU governor Interactive. This uses a completely different algorithm to decide when to increase or decrease the GPU frequency. Also the functions tz_wake and tz_sleep don't do anything, they were a bit useless at this point after some testing.

kgsl: add back content to the sleep function for this tz routine. Also fix the length of the governor name for the sysfs entry.
