PM / devfreq: Move struct devfreq_governor to devfreq directory

Browse source 
This patch moves the struct devfreq_governor from header file
to the devfreq directory because this structure is private data
and it have to be only accessed by the devfreq core.

/**
* struct devfreq_governor - Devfreq policy governor
* @node: list node - contains registered devfreq governors
* @name: Governor's name
* @immutable: Immutable flag for governor. If the value is 1,
* this govenror is never changeable to other governor.
* @get_target_freq: Returns desired operating frequency for the device.
* Basically, get_target_freq will run
* devfreq_dev_profile.get_dev_status() to get the
* status of the device (load = busy_time / total_time).
* If no_central_polling is set, this callback is called
* only with update_devfreq() notified by OPP.
* @event_handler: Callback for devfreq core framework to notify events
* to governors. Events include per device governor
* init and exit, opp changes out of devfreq, suspend
* and resume of per device devfreq during device idle.
*
* Note that the callbacks are called with devfreq->lock locked by devfreq.
