Checkpoint a work in progress:
o Use the common pci_* routines in preference to the copied and hacked routines from an ancient pci.c. This saves 509 lines in cardbus.c. More savings to follow when I convert the resource code over. In the past when I've done this the resource code conversion breaks cardbus in subtle ways so I'm doing a 1/2 way checkpoint this time. cardbus still works for me the same as it did before. It also looks like cardbus devices now show up as pci bus devices to pciconf -l, but maybe that was happening before. Inspired by a patch from Justin Gibbs many moons ago. When he finishes his kobj multiple inheritance work, we can transition the finished version of this work to that fairly easily.
