The pvr driver requires that the memory bus speed is kept fast while the
GPU is active. Since the memory bus speed is tied to the CPU frequency,
pvr (previously) used a cpufreq notifier called on policy updates to ensure
the CPU is running at a minimum 200 MHz while active. The problem with
this approach is that any changes to scaling_min_freq while the GPU is
active (e.g., while interacting with the Processor settings menu) get
clamped to 200 MHz, which persists even when the GPU is inactive.
By switching to DVFS locks, changes to scaling_min_freq persist, and so
allows the use of 100 MHz when the GPU is inactive. Fixes epiccm #14.

This reverts commit 463e99c53ae3b7c18ad3bee3825d4d75c603adae
See Andrew Dodd's comments on http://review.cyanogenmod.com/#/c/19820/.
Also been getting rare homescreen corruption after moving PVR to DVFS lock.

On s5pv210 the cpufreq lower frequencies affect the memory bus
which in turn affects the GPU when it is actually busy.
To avoid cpufreq impacting the GPU when it is busy, the GPU
now tweaks the policy's min freq based on its activity.
