change of guaranteed is caused by user space action, so user space knows
that guarantee will change.
This series causes user space to trigger scaling_max_freq update with

The mmio offset range can be different based on the PCI device id. Here
for INTEL_RAPL_PRIO_DEVID_1, the range is increased from 45 to 64. Pass
the range as the driver_data. Also account for different ranges during
