add newer pci infrastructure

This code does not negatively affect existing pci support and existing
pci devices, it introduces parallel infrastructure which:
- allows users to define a private which could be device specific.
  This avoids doing multiple lookups, which massively helps the ati spi
  driver which will support hundreds of devices.
- uses linux sysfs pci infrastructure for enable/disable and mapping
  resources. This circumvents the security restrictions surrounding
  /dev/mem, but means that support for other operating systems still
  needs to be cobbled together.
- looks up device names through libpci, keeping us from maintaining a
  separate names list.
