Add a configuration file for the Atheros PB47 reference board. This is an AR71xx based board with 8MB flash, 64MB RAM, a Mini-PCI+ slot (see below) and a single 10/100/1000baseT ethernet port. It also has two USB ports. This is an easier board than most to add as it doesn't have a switch PHY on-board. This made it (mostly) trivial to craft a working configuration. Things to note: * This, like most other reference boards, use uboot rather then redboot. It means that you typically have to manually flash both the kernel and rootfs partitions. * Since there's currently no (nice) way to extract out the ethernet MAC and RAM from the uboot environment, the RAM will default to 32mb and the MAC will be something very incorrect. I'll try to fix this up in a subsequent commit or two, even if it's just some hard-coded nonsense in ar71xx_machdep.c for now. * The board is designed for a specific model of mini-PCI+ NIC which never made it into production. Normal mini-PCI NICs will work fine; if you happen to have the NIC in question then it will work fine with this board.

This isn't required any longer - it turns out the flash has ~ 1.7MB of space for a kernel. There's thus plenty of space for a full, non-module kernel.

Use geom_uncompress now, rather than geom_uzip. This results in a much smaller rootfs image and it easily fits in the 8MB flash.
