Juli Mallett 3032f6daa2 Flesh out PCI bus support some:
o) Reset and configure the bus from scratch rather than expecting U-Boot to
   do it for us.  Values and configuration from Linux, U-Boot and comments
   in the Cavium Simple Executive sources.
o) Do a resource assignment and bus numbering pass in the absence of a PCI
   BIOS or firmware that will do it for us.
   XXX This has to be the third or fourth instance of this in FreeBSD and
       it would be nice to have it become part of the PCI bus driver itself,
       like it is on Linux.
o) Fix interrupt mapping for and adjust bus configuration for the Lanner
   MR-955, based on information provided by Lanner.
