drm/i915/rps: Add frequency translation helpers
Add two helpers that for reading the actual GT's frequency. The
two helpers are:
- intel_rps_read_cagf: reads the frequency and returns it not
normalized
- intel_rps_read_actual_frequency: provides the frequency in Hz.
Use the above helpers in sysfs and debugfs.
