[netdrvr] forcedeth: improved probe info; dev_printk() cleanups 



main change:
* greatly improve per-NIC probe diagnostic output.  Similar to other
  net drivers, print out MAC address, PHY info, and various hardware and
  software flags that may be relevant.

other changes:
* similar to other net drivers, only print the initial version message
  when we have found at least one board.

* don't bother to print error message when pci_enable_device() fails,
  it will do so for us.

* use dev_printk() rather than printk() in nv_probe().  This gives
  use a standardized output similar to the rest of the kernel, and
  eliminates the need to manually print out PCI bus id.

* use DRV_NAME constant where appropriate

* clean struct pci_driver indentation
