[U-Boot] [PATCH 28/29] blackfin: Set up the debug UART if enabled

[Simon Glass]

The debug_uart function is useful for debugging early init problems. While
blackfin has its own means of doing this, it would be better to support
the standard approach. Add a call to init the debug UART early in
start-up.
