pnp: Implement common handling for PnP config modes
Many super i/o chips only answer to PnP requests if they are in a configuration state (sometimes also called ext func mode). To cope with that, the code of many chips implements its own version of our default PnP functions like pnp_set_resource(), pnp_enable_resource() etc. To avoid this code duplication, this patch extends our PnP device interface with optional functions to enter and exit configuration mode.
