Folks,
please take this patch as an attempt to renew old discussion or rather
start a new one focused solely on importing new ARM CMSIS code which is
(i) under Apache 2 license but (ii) without any NOTICE file.
I hope technical advantages are huge and there is no hinder involved
like with other possible Apache2 licensed projects with NOTICE file
presented.
The patch itself is clear replace of existing files with a new files,
plus required files added and old one not needed anymore removed.
The patch was very lightly tested by building several ARM BSPs
especially those affected by the change.
Thanks for any comments!

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.
