Add sysfs interfaces for CPPC autonomous selection in the cppc_cpufreq
driver.
The patch series is organized in two parts:
- patch 1 refactor out the general CPPC register get and set functions
in cppc_acpi.c
- patches 2-3 expose sysfs files for users to control CPPC autonomous
selection when supported
