ACPI: Fan: Drop force_power_state acpi_device option
force_power_state was used as a workaround for invalid cached power state of the device. We do not cache power state, so no need for workaround. Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Acked-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>
