ACPI / Fan: Rework the handling of power resources

Browse Source 
Use the new function acpi_bus_update_power() for manipulating power
resources used by ACPI fan devices, which allows them to be put into
the right state during initialization and resume.  Consequently,
remove the flags.force_power_state field from struct acpi_device,
which is not necessary any more.
