[ACPI] Always set P-state on initialization
Otherwise a platform that supports ACPI based cpufreq and boots up at lowest possible speed could stay there forever. This because the governor may request max speed, but the code doesn't update if there is no change in speed, and it assumed the initial state of max speed. http://bugzilla.kernel.org/show_bug.cgi?id=4634 Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
