printk: Change type of CONFIG_BASE_SMALL to bool

Browse Source 
CONFIG_BASE_SMALL is currently a type int but is only used as a boolean.

So, change its type to bool and adapt all usages:
CONFIG_BASE_SMALL == 0 becomes !IS_ENABLED(CONFIG_BASE_SMALL) and
CONFIG_BASE_SMALL != 0 becomes  IS_ENABLED(CONFIG_BASE_SMALL).
