pciconf: Add a tree mode
This lists PCI devices in a hierarchy showing the parent/child
relationship of PCI devices and bridges. While this is inspired by
lspci -t output, the format is closer to ps -d and also prefers using
new-bus device names when possible. If a device does not have a
driver, the PCI selector is output in place of the device name.
When the -v flag is given, the vendor and device ID strings are output
after the device name. If a string for an ID isn't found, the hex ID
values are output instead.

I did play with enabling some of other list options like -b and -B to output
as indented under each node in the tree. If there is a desire for that, I could
add it. I found it a bit distracting when I prototyped it. OTOH, it might be
useful for -c at least. One of the things I think is helpful in this view is
that you can easily see the PCI bridge that is the upstream port of a PCI-e
link connecting to a leaf device.
