The boost feature can be controlled at two levels currently, driver level (applies to all policies) and per-policy. Currently the driver enables driver level boost support from the per-policy ->init() callback, which isn't really efficient as that gets called for each policy and then there is online/offline path too where this gets done unnecessarily. Instead set the .set_boost field directly and always enable the boost support. If a policy doesn't support boost feature, the core will not enable it for that policy. Keep the initial state of driver level boost to disabled and let the user enable it if required as ideally the boost frequencies must be used only when really required.
