this patch must be applied after PnP patch v0.94. It contains my
small cleanups of PnP code and I tried to rewrite almost all ISA PnP
drivers to new PnP subsystem except sound drivers (ALSA & OSS).

  PnP update
    - separated dev->resource to dev->io_resource and dev->mem_resource
    - added pnp_*_valid() macros
    - added status member to pnp_card structure
    - added pnp_device_attach/detach functions
    - added pnpc_attach/detach functions
    - moved pnp_find_card() and pnp_find_dev() functions to isapnp.h
    - updated IDE/gameport/ISDN/network/scsi/radio/telephone drivers
      to latest PnP code
