devfreq: Use devfreq_update_stats for gpu governors

Browse Source 
This is the recommended way of using the devfreq api from
within governors. The devfreq_update_stats() will utilize the
devfreq.last_status to get the target device status so we no
longer need to declare a local variable to get the target
status.
