[PATCH v4 23/24] PM / devfreq: tegra30: Increase sampling period to 16ms

[Dmitry Osipenko]

Increase sampling period by 4ms to get a nicer pow2 value, converting
diving into shifts in the code. That's more preferable for Tegra30 that
doesn't have hardware divider instructions because of older Cortex-A9 CPU.
In a result boosting events are delayed by 4ms, which is not sensible in
practice at all.
