Blackfin Serial Driver: fix baudrate for early_printk

Since we already setup the early console UART in
arch/blackfin/kernel/early_printk.c, and common functions which are
enabled from the .setup will override the proper settings later, don't
fill in these structures.  Otherwise we get mangled baudrate settings when
using early_printk.
