msm: hotplug: Update default fast_lane_load

A value of 99% load catches almost all spikes and keeps spurious
onlinings to an absolute minimum.

Replace all instances of cputime64_t by u64 (see upstream commit
72a4ce340a7ebf39e1c6fdc8f5feb4f974d6c635).
cpufreq: interactive: Move definition of cpufreq_gov_interactive downwards

This moves definition of cpufreq_gov_interactive towards the bottom of file, so
that we don't have to add prototype of cpufreq_governor_interactive() in the
beginning of file.

GPU OC: Smoother Ramp up

* Rather than having two 320 MHz steps lets go from 320 MHz to 389 MHz then to 450 MHz so it's not as crazy of a jump
