SIMPLE GPU ALGORITHM: Fix stuck on low GPU greq after adding more GPu STEPS!

After commit https://github.com/dorimanx/Dorimanx-LG-G2-D802-Kernel/commit/f13203708dd07220ca5c1892c0110b9deef31386 and https://github.com/dorimanx/Dorimanx-LG-G2-D802-Kernel/commit/07264550123b131dff09eb17f76c3e3729786a9a
With msm adreno tz gov and simple_gpu_activate set to 1
i was stuck on 100Mhz as new steps changed the logic.

on idle before patch:
level is 6
bus.num = 4 and it's static!
bin.busy_time = 1000~8000 but only if it's set as (unsigned int)priv->bin.busy_time !!!

on idle after patch!
level is 6
bus.num = 6 STATIC!
bin.busy_time = 1000~8000 so we can check > ramp_up_threshold

@faux123 this why freq was not going UP with msm adreno tz when using this mod.
when mode was OFF. freq was going up as should.

but using this mode i can hold the freq longer on high freq. and that is COOl.
