[PATCH] PM: devfreq: init performance/powersave governor

[Xiaoguang Chen <chenxg@marvell.com>]

Performance and powersave governor's get_target_freq
is not called if driver chooses one of these two governors.
Add init function in governor profile to call update_devfreq
which will call get_target_freq subsequently.
