altos/stm: Add comments to the .ld files explaining how the romconfig stuff works
Would be nice to be able to explicitly define addresses for the
romconfig variables, but I can't figure out how to make that
work. Instead, just explicitly load the files in teh right order to
make things land in the right places.
