It seems that the black-box GPU frequency selection algorithm is unaware
of high refresh rates, and assumes a refresh rate of 60 Hz for its
target frequencies. This results in frequencies that are too low being
selected when a higher refresh rate, such as 90 Hz, is used.
To remedy this, multiply the GPU's busy time by a ratio of the current
refresh rate to 60 Hz. This makes msm-adreno-tz select the right
frequencies needed to avoid stuttering.

- Actually make it work with real-time dynamic refresh rate
