ACPI / processor: Get power info before updating the C-states
acpi_processor_get_power_info() has to be called before acpi_processor_setup_cpuidle_states() to have the latest information available. This fixes the missing C-state information after AC-->DC transition. Signed-off-by: Thomas Schlichter <thomas.schlichter@web.de> Cc: <stable@vger.kernel.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
