tpm: Enable TCG_TPM2_HMAC by default only for X86_64
Given the not fully root caused performance issues on non-x86 platforms,
enable the feature by default only for x86-64. That is the platform it
brings the most value and has gone most of the QA. Can be reconsidered
later and can be obviously opt-in enabled too on any arch.
