[U-Boot] [PATCH 4/4] MIPS: call debug_uart_init right before board_init_f

From: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

All MIPS boards that support debug uart are calling debug_uart_init right at
the beginning of board_early_init_f.
Instead of doing that, let's provide a generic call to debug_uart_init right
before the call to board_init_f if debug uart is enabled.
