[PATCH v2 3/4] qemu: Default to TPM 2.0 in most scenarios
TPM 1.2 is a pretty bad default these days, especially for
architectures which were introduced when TPM 2.0 already existed.
We're already carving out exceptions for several scenarios, but
that's basically backwards: at this point, using TPM 1.2 is the
exception.
Restructure the code so that it reflects reality and we don't
have to remember to update it every time a new architecture is
introduced.
