CONFIG_BASE_FULL is equivalent to !CONFIG_BASE_SMALL and is enabled by
default: CONFIG_BASE_SMALL is the special case to take care of.
So, remove CONFIG_BASE_FULL and move the config choice to
CONFIG_BASE_SMALL (which defaults to 'n')

For defconfigs explicitely disabling BASE_FULL, explicitely enable
BASE_SMALL.
For defconfigs explicitely enabling BASE_FULL, drop it as it is the
default.
