hwrng: Add quality parameter to msm-rng driver 



With the recent changes in upstream, certain parameters
are updated in the core random number generator driver.
So update HW rng driver to provide the quality estimation
of true entropy in RNG's bitstream. Value 700 corresponds
to 70% an arbitrary value, which is taken from 3.10.
