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.
