Title: Split up source files in groups

**Note: Do not merge**

Split up source files in three groups to make projects more friendly to use.

If this is considered an improvement I will do a proper pull request to master.
Note that the KL25Z, LPC11U24 and LPC1347 did not have the --c99 setting for c files before, please verify if this is intended or not.
