> Existing implementation checks all divider values and tracks 'red' proximity value
> for the frequency.
> 
> But as divider array is monotonically increasing the first divider that gives DMIC
> rate in 3MHz range is the best one we should use. No need for 'red' zone tracking.
> 
> Additionally make sure that DMIC frequency is higher 1MHz.
