Subject: Kconfig.debug: make DEBUG_INFO always default=n
While trying to make sure CONFIG_DEBUG_INFO wasn't set for COMPILE_TEST, I
ordered the choices incorrectly to retain the prior default=n state. Move
DEBUG_INFO_NONE to the top so that the default choice is disabled, and
remove the "if COMPILE_TEST" as it is now redundant.
