PM / devfreq: Move statistics to separate struct devfreq_stats
Count time and transitions between devfreq frequencies in separate struct devfreq_stats for improved code readability and maintenance. Signed-off-by: Kamil Konieczny <k.konieczny@samsung.com> Reviewed-by: Matthias Kaehlcke <mka@chromium.org> [cw00.choi: Fix the merge conflict in trasn_stat_store and use 'devfreq->stats.*' style for consistent coding style and restore the clean-up code of 'devfreq->profile->*'] Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
