cmsis_dsp: transform: error during building cf64.fpu and rf64.fpu for mps2_an521_remote

[gopiotr]

Describe the bug
Tests libraries.cmsis_dsp.transform.cf64.fpu and libraries.cmsis_dsp.transform.rf64.fpu from tests/lib/cmsis_dsp/transform cannot be built for mps2_an521_remote platform.

To Reproduce
Steps to reproduce the behavior:

1. Run Twister by command:

./scripts/twister --inline-logs -v -v --overflow-as-error -p mps2_an521_remote -T tests/lib/cmsis_dsp/transform -s tests/lib/cmsis_dsp/transform/libraries.cmsis_dsp.transform.cf64.fpu -s tests/lib/cmsis_dsp/transform/libraries.cmsis_dsp.transform.rf64.fpu

2. Observe output logs - especially those from building process

Expected behavior
Test should be able to build on mps2_an521_remote platform, or limits in test scenario definition (in testcase.yaml file) should be changed to exclude this platform (then also integration_platform entry should be changed).

Impact
Test introduce misleading information, that cf64.fpu and rf64.fpu tests can be run on mps2_an521_remote, but in fact they can't be.

Same as #44947 (comment)

[gopiotr]

Okay, so is there any sense to keep in integration_platform entry with mps2_an521_remote platform?

Fair enough, a different integration platform should be specified in this case.

[stephanosio]

will fix this after #45319 by replacing mps2_an521_remote with mps2_an386.
