hw/arm/aspeed: Add fby35 machine type 

Add the 'fby35-bmc' machine type based on the kernel DTS[1] and userspace
i2c setup scripts[2]. Undefined values are inherited from the AST2600-EVB.

Reference images can be found in Facebook OpenBMC Github Release assets
as "fby35.mtd". [3]

You can boot the reference images as follows (fby35 uses dual-flash):

qemu-system-arm -machine fby35-bmc \
    -drive file=fby35.mtd,format=raw,if=mtd \
    -drive file=fby35.mtd,format=raw,if=mtd \
    -nographic
