Sharat Masetty a2c3c0a54d drm/msm/a6xx: Add devfreq support for a6xx ...

Implement routines to estimate GPU busy time and fetching the
current frequency for the polling interval. This is required by
the devfreq framework which recommends a frequency change if needed.
The driver code then tries to set this new frequency on the GPU by
sending an Out Of Band(OOB) request to the GMU.
