bsps/arm: replace CMSIS v4 with CMSIS v5 files
CAVEAT: license change from BSD to Apache2 license!
Explanation:
The imported files come from CMSIS v5 project available on:
https://github.com/ARM-software/CMSIS_5/tree/develop
The files imported are located inside the CMSIS/Core/Include
project sub-directory.
The project does not provide any NOTICE file in its root directory nor
in the directory of the imported files.
The NOTICE file and its usage in the Apache 2 license was/is
so far the only issue mentioned in discussion of RTEMS developers/users
when considering inclusion of the code under Apache 2 license
into the RTEMS project.
Since the CMSIS v5 project is free from this legal hinder, we may freely
use it and update files to the latest version.
Technical: the patch replaces code from 2015 with the latest version
which brings quite a lot of bug fixes and most importantly opens
possibilities to support MCUs based on new ARM cores.
