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.
