cpufreq: Return -EOPNOTSUPP if no policy supports boost

Browse Source 
In cpufreq_boost_trigger_state(), if none of the the policies support
boost, policy_set_boost() will not be called and this function will
return 0.

But it is better to return an error to indicate that the platform
doesn't support boost.
