sh: cpufreq: notify about rate rounding fallback. 



The general case for platforms that support the clock framework fully
will be rate table rounding, while others will have to fall back on much
coarser general rate rounding. Notify about it during boot so the limited
functionality for the given subtype is appropriately noted.
