[PATCH v4 1/5] efi: stub: Define debug uart functions only if CONFIG_DEBUG_UART is enabled

[Lukasz Czechowski]

Initialize the debug uart only in case CONFIG_DEBUG_UART is
enabled. The _debug_uart_putc is used internally by debug uart
functions, so it must be also included inside #ifdef block,
otherwise it will cause compilation warnings.
