Replace BSD custom PCI code with a stub implementation thanks to pciaccess.

Note that pciaccess doesn't yet have Net/OpenBSD support, but the relevant
code should go there instead of disconnected code in the X Server.

While here, remove the now-disabled INCLUDE_XF86_NO_DOMAIN from the headers,
and un-disable xf8StdAccResFromOS for those OSes without domain support which
will need it.
