[PATCH 04/11] cpufreq: Initialize kobj_type release callback in ondemand and conservative governors

[Ian Rogers]

Export cpufreq_dbs_data_release() and set .kobj_type.release in the
ondemand and conservative governors so their gov_attr_set kobjects have
a valid release callback, matching cpufreq_ governor_dbs.

This prepares for annotating struct kobj_type::release with
__require_explicit_initialization.

Fixes: c4435630361d ("cpufreq: governor: New sysfs show/store callbacks for 
governor tunables")
