MIPS: call debug_uart_init right before board_init_f
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 for boards without
stack in SRAM.
On the other hand, boards with stack in SRAM can call earlier (right before
low level init).
