cpufreq: Simplify core code related to boost support
Notice that the boost_supported field in struct cpufreq_driver is redundant, because the driver's ->set_boost callback may be left unset if "boost" is not supported. Moreover, the only driver populating the ->set_boost callback is acpi_cpufreq, so make it avoid populating that callback if "boost" is not supported, rework the core to check ->set_boost instead of boost_supported to verify "boost" support and drop boost_supported which isn't used any more.
