examples: Remove duplicate example linker scripts.
Only add one linker script per eval board, and have the Makefiles use that. This avoids duplication, and various copy-paste errors and left-overs which we already have in the tree. Some of the linker scripts are not really correct, yet. Both, the comments which say which board, chip, and RAM/ROM sizes are used, as well as the actual RAM/ROM size definitions are sometimes copy-pasted from other boards and are thus incorrect. This needs to be fixed.
