This patch removes the warning generated when including cmsis_iar.h from applications using CMSIS 5.1 and older. The warning will still be generated for CMSIS 5.2 and later since cmsis_iar.h is deprecated from that release onwards.
The following error message was generated:

Warning: The header file 'cmsis_iar.h' is obsolete and should not be used.
A suitable version is automatically included from the CMSIS-core package.
This file will be removed in a future release.
