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



commit 7be0d19c751b02db778ca95e3274d5ea7f31891c 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: 99b2fc2b ("ARM: SAMSUNG: Use debug_ll_addr() to get UART base address")
