[CPUFREQ][2/8] acpi: reorganize code to make MSR support addition easier

Browse source

Some clean up and redsign of the driver. Mainly making it easier to add
support for multiple sub-mechanisms of changing frequency. Currently this
driver supports only ACPI SYSTEM_IO address space. With the changes
below it is easier to add support for other address spaces like Intel
Enhanced Speedstep which uses MSR (ACPI FIXED_FEATURE_HARDWARE) to do the
transitions.
