[PATCH v3 07/10] drm/panthor: devfreq: make get_dev_status use get_cur_freq

The only device-specific part of panthor's get_dev_status devfreq
callback is getting the clock frequency. All the other logic surrounding
what it does may be useful for other devfreq implementations however.

Make it call into get_cur_freq instead of poking the common clock
framework directly.
