Next step towards pcic_pci: the ability to allocate mapped memory in attach.

o Introduce flags word to the softc.  This will be used to control various
  aspects of the driver.  Right now there are two bits defined, PCIC_IO_MAPPED
  and PCIC_MEM_MAPPED.  One for ISA cards that are I/O mapped, the other is
  for PCI cards that are memory mapped.  Only the ISA side is implemented
  with this commit.
o Introduce a pcic_dealloc which will cleanly dealloc resources used.  Right
  now it is only supported when called from probe/attach.
o Keep track of resources allocated in the pcic_softc.
o move pcictimeout_ch to the softc so we can support multiple devices
  in polling mode.
o In ISA probe, set PCIC_IO_MAPPED.
o Introduce and compute the slot mask.  This will be used later when
  we expand the number of slots on ISA from 2 to 4.  In such a case, we
  appear to have to use polling mode otherwise we get two different cards
  trying to drive the same interrupt line.  I don't have hardware to
  test this configuration, so I'll stop here.
