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

commit 7be0d19c75 upstream.

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: 99b2fc2b8b ("ARM: SAMSUNG: Use debug_ll_addr() to get UART base address")

Say Y here if you want verbose debugging from the PM Suspend and
Resume code. See <file:Documentation/arm/samsung-s3c24xx/suspend.rst>
