Joerg Wunsch 72821110ac Overhaul of the pcii driver:
. Properly allocate all IO space resources.  These cards scatter their
  IO addresses over a range of 0x1600 bytes, and they require an
  additional address for "special interrupt handling".

. Implement the "special interrupt handling" per the GPIB-PCIIA
  Technical Reference Manual; this was apparently not declared for the
  clone card this driver has been originally implemented for, but it
  turned out to be needed for both, an original NI brand PCII/PCIIA
  card as well as the Axiom AX5488 clone.

. Add some diagnostic messages for various resource allocation etc.
  failures during probe.

. Add some comments about the structure of the IO address space that
  is used by these cards.
