Update to 5.6.1

MSP432R Core Release v4.9.1

This is a minor update to the initial release. This release fixes an issue for an undefined reference to analogRead(). This was due to 2 files with the same name but in a different directory being overwritten when create core.a with ar. Adding P to the command line arguments provided to ar solved the issue.
