EFR32 Device Attestation Credentials provider bugfix.

[rcasallas-silabs]

Problem

SignWithDeviceAttestationKey now receives the full message, instead of the message hash. The signature calculation therefore has to be modified accordingly.

Change overview

Signature calculation changed from psa_sign_hash to psa_sign_message.

Testing

Tested on EFR32. This changes only had effect on EFR32, and only if the flag chip_build_platform_attestation_credentials_provider is set to true.

@woody-apple Is this something that could be cherry-picked in the SVE branch?
