aspeed: Add AST1030 (BIC) to fby35

aspeed: Add AST1030 (BIC) to fby35

With the BIC, the easiest way to run everything is to create two pty's
for each SoC and reserve stdin/stdout for the monitor:

    wget https://github.com/facebook/openbmc/releases/download/openbmc-e2294ff5d31d/fby35.mtd
    wget https://github.com/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf
    qemu-system-arm -machine fby35 \
        -drive file=fby35.mtd,format=raw,if=mtd \
        -device loader,file=fby35.mtd,addr=0,cpu-num=0 \
        -serial pty -serial pty -serial mon:stdio -display none -S

    screen /dev/ttys0
    screen /dev/ttys1
    (qemu) c

This commit only adds the the first server board's Bridge IC, but in the
future we'll try to include the other three server board Bridge IC's
too.
