where it looks straightforward, and pci_aprint_devinfo_fancy in a few
others where drivers want to supply their own device names instead
of the pcidevs generated one. More complicated cases, where names
are composed at runtime, are left alone for now. It certainly makes
sense to simplify the drivers here rather than inventing a catch-all API.
This should serve as as example for new drivers, and also ensure
consistent output in the AB_QUIET ("boot -q") case. Also, it avoids
excessive stack usage where drivers attach child devices because the
buffer for the device name is not kept on the local stack anymore.
