Users should use no_console_suspend if they want output during suspend, rather than relying on DEBUG_LL. Using DEBUG_LL has two disadvantages: 1. It doesn't respect power management. When the UART is suspended the clock is stopped, and trying to use DEBUG_LL will just hang. This means if the user selects CONFIG_SAMSUNG_PM_DEBUG but does NOT disable console suspend, the system will hang during suspend. 2. It skips syslog and other console devices such as pstore.
