msm: vidc: tune dynamic framerate logic 



Some vp9 clips contains alt-ref frames(decode only) at
periodic intervals and that particular frames buffer ts
delta is very low(as low as 1 ms). So dynamic framerate
calculation in driver is going for a toss.

To mitigate above problem, taking avg framerate instead
of max value.
