Volker Ruppert ae180cc46a - pci slot register mechanism added
* up to 5 slots can be specified with the 'i440fxsupport' config option
  * the pci slot number are hardwired to pci device numbers
  * the 'devfunc' value is returned the calling device (useful for multi-function
    devices)
  * the core of the i440FX chipset is hardwired to pci device 1 + 2; usb is still
    optional and appears at device 1, function 2
- ne2k: enable pci features if connected to a pci slot
- ne2k: asic data port supports 32-bit access if ne2k-pci is active
- pci2isa: improved error messages for ELCR1 and ELCR2
