ARM: samsung: fix PM debug build with DEBUG_LL but !MMU

Selecting CONFIG_SAMSUNG_PM_DEBUG (depending on CONFIG_DEBUG_LL) but without CONFIG_MMU leads to build errors: arch/arm/plat-samsung/pm-debug.c: In function ‘s3c_pm_uart_base’: arch/arm/plat-samsung/pm-debug.c:57:2: error: implicit declaration of function ‘debug_ll_addr’ [-Werror=implicit-function-declaration] Fixes: 99b2fc2 ("ARM: SAMSUNG: Use debug_ll_addr() to get UART base address") Reported-by: kernel test robot <[email protected]> Signed-off-by: Krzysztof Kozlowski <[email protected]> Cc: <[email protected]> Link: https://lore.kernel.org/r/[email protected]
