s/larger/some :)

So we can change all the callers of cpufreq_frequency_table_target(),
like the governors, ondemand-bias stub drivers, core, etc and call
the dedicated 'relation' specific routines directly, as we mostly know
in advance the 'relation' in which we want to update the freq.

And, so doing that with a dedicated patch might be better.
