Masahiro Yamada 8e2615752e bd_info: remove bi_barudrate member from struct bd_info
gd->bd->bi_baudrate is a copy of gd->baudrate.

Since baudrate is a common feature for all architectures,
keep gd->baudrate only.

It is true that bi_baudrate was passed to the kernel in that structure
but it was a long time ago.
