tpm: Allow separate handling of Google Ti50 TPM
A new iteration of Google's TPM implementation will advertize a new
DID:VID, but otherwise follow the same protocol as the earlier design.
This change makes use of Kconfigs TPM_GOOGLE_CR50 and TPM_GOOGLE_TI50
to be able to take slightly different code paths, when e.g. evaluating
whether TPM firmware is new enough to support certain features.
