lib: at_parser: move generated code and ignore formatting
Browse files Browse the repository at this point in the history 
Moves the generated `at_match.c` to the `generated` directory
and adds this directory to the excluded list for Checkpatch,
so that the generated file does not require reformatting.
This makes versioning easier since it removes the reformatting
step necessary to comply with Checkpatch.
