We shouldn't prompt for SYS_BOARD / SYS_CONFIG_NAME and instead just
provide the values here.

You should probably use the "N:" syntax here and say "N: an7581" to
catch all the files later on too. Perhaps also "N: airoha" to catch the

This doesn't appear to be the output of "make savedefconfig" so please
re-sync it with that.

You cannot set CONFIG symbols in this file anymore.
