thermal: gov_fair_share: Rearrange get_trip_level()

Browse source 
Make get_trip_level() use for_each_trip() to iterate over trip points
and make it call thermal_zone_trip_id() to obtain the integer ID of a
given trip point so as to avoid relying on the knowledge of struct
thermal_zone_device internals.

The general functionality is not expected to be changed.

This change causes the governor to use trip pointers instead of trip
indices everywhere except for the fair_share_throttle() second argument
that will be modified subsequently along with the definition of the
governor .throttle() callback.
