mofd-common: init: Make ondemand a little less on demand

Turn off io_is_busy which helps reduce the power consumption
when doing things like playing youtube videos (slightly).

For lower frequencies, enable a tiny powersave_bias.  That will
target lower frequencies and should cause us to idle more often
at min frequency and generally slide the frequency utilizations
down a little bit.  Cap the bias at a low frequency though so
we don't sacrifice top end performance for lower end power savings.
