briggs c6daae9b79 Add an option (defopt) PCI_NETBSD_CONFIGURE that provides PCI bus
configuration (assignment of bus numbers, BARs, timer values,
interrupt lines, etc.).
The interface must be called from m.d. code prior to probing the bus.
It is meant to be called once for each primary (bus == 0) PCI bus in
the system.  It will configure any busses behind PCI-PCI bridges.
Section 9 man page for pci_configure_bus() will come soon.
In the meantime, sample usage is in arch/sandpoint/sandpoint/mainbus.c.
