[PATCH v2 11/11] RISC-V: make it possible to build RV32I multi-image with DEBUG_LL=n

[Antony Pavlov]

Building multi-image with these options:

CONFIG_ARCH_RV32I=y
CONFIG_RISCV_M_MODE=y
CONFIG_SOC_ERIZO=y
CONFIG_BOARD_ERIZO_GENERIC=y
CONFIG_SOC_LITEX=y
CONFIG_BOARD_LITEX_LINUX=y
CONFIG_DEBUG_LL=n

leads to the build error:

arch/riscv/boards/erizo/lowlevel.c: In function ‘__start_erizo_generic’:
arch/riscv/boards/erizo/lowlevel.c:11:2: error: implicit declaration of
function ‘debug_ll_ns16550_init’ [-Werror=implicit-function-declaration]
   11 |  debug_ll_ns16550_init();
      |  ^~~~~~~~~~~~~~~~~~~~~

This patch fixes the problem by using preprocessor's directive.
