platform: nordic: Fix invalid config for CRYPTO_NV_SEED

TF-M demands that either CRYPTO_NV_SEED or CRYTPO_HW_ACCELERATOR is
enabled. Since we don't support HW accelerator in-tree we need to
enable CRYPTO_NV_SEED again, even though this is only a hardcoded value.

This reverts commit 1ac50c2dc79c1bdc85589c71c09f69207055c12e.
