Attest: Register attestation key to crypto

Initial attestation key is provisoned in the SoC during
fabrication. It must be obtained from platform layer and
registered to crypto partition for further usage. This key
is used to sign the initial attestation token (IAT).

Unregister the initial attestation test suite from the
TFM_LVL == 3 compatible test suite list. This is needed,
because this patch introduces partition-to-partition calls
between attestation and crypto partition and crypto
partition currently does not support TFM_LVL == 3 execution.
