[PATCH 09/14] xfree86: remove IOADDRESS definition from common header file

[Tiago Vignatti]

IOADDRESS currently is used to store I/O addresses - actually the virtual
address of I/O ports. In theory it should be used for any kind of bus that
would access devices through this method. However, in practice we're abusing
such definition in the implementation:

  1. we're narrowing it because it's defined inside os-support/bus/xf86Pci.h,
     i.e., for PCI buses only, and;

  2. we're extending its usage to common/ files, which conceptually shouldn't
  be aware of any hardware details.

This patch try to contour 2., substituting all references of IOADDRESS inside
common/ by unsigned long. Therefore IOADDRESS should be used only for PCI from
now.

One may want to improve this patch creating a similar type inside DDX common
directory (common/) to deal with buses in general.
