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.

I think we should move this inside the "#ifndef CONFIG_MIPS_INIT_STACK_IN_SRAM ... #endif" block and also add this in the "#ifdef CONFIG_MIPS_INIT_STACK_IN_SRAM ... #endif" block above. This way a SoC can use debug_uart also in lowlevel_init if it supports the initial stack in SRAM with option CONFIG_MIPS_INIT_STACK_IN_SRAM.
