Rafael J. Wysocki 22c52fa515 ACPI: processor: thermal: Update CPU cooling devices on cpufreq policy changes ...

When a cpufreq policy appears or goes away, the CPU cooling devices for
the CPUs covered by that policy need to be updated so that the new
processor_get_max_state() value is stored as max_state and the
statistics in sysfs are rearranged for each of them.

Do that accordingly in acpi_thermal_cpufreq_init() and
acpi_thermal_cpufreq_exit().

Fixes: a365105c685c("thermal: sysfs: Reuse cdev->max_state")
