aspeed: Add AST1030 (BIC) to fby35

Browse Source 
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/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf

        -device loader,file=fby35.mtd,addr=0,cpu-num=0 \
        -serial pty -serial pty -serial mon:stdio -display none -S

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.
