This adds a new machine type "fuji-bmc" that's equivalent to
"ast2600-evb" except that it uses MAC3 and UART1. It might be
appropriate to change other aspects of this machine type in the future,
but so far this is all the specificity necessary to get a Fuji OpenBMC
image booting and networking within QEMU.

Here's a link to the device tree:

https://github.com/facebook/openbmc-uboot/blob/openbmc/helium/v2019.04/arch/arm/dts/aspeed-bmc-facebook-fuji.dts

I tested this by building a Fuji image from Facebook's OpenBMC repo,
booting it, and ssh'ing into it.

git clone https://github.com/facebook/openbmc
cd openbmc
./sync_yocto.sh
source openbmc-init-build-env fuji build-fuji
bitbake fuji-image
dd if=/dev/zero of=/tmp/fuji.mtd bs=1M count=128
dd if=./tmp/deploy/images/fuji/flash-fuji of=/tmp/fuji.mtd \
    bs=1k conv=notrunc

git clone --branch aspeed-next https://github.com/peterdelevoryas/qemu
cd qemu
./configure --target-list=arm-softmmu --disable-vnc
make -j $(nproc)
./build/arm-softmmu/qemu-system-arm \
    -machine fuji-bmc \
    -drive file=/tmp/fuji.mtd,format=raw,if=mtd \
    -serial stdio \
    -nic user,hostfwd=::2222-:22

I also created a Github release with the Fuji mtd image and added an
acceptance test utilizing it.
