security/tpm: resolve conflicts in TSS implementations

No functional changes.  Refactor code such that there won't be any
compiler or linker errors if TSS 1.2 and TSS 2.0 were both compiled
in.

One might want to support both TPM families for example if TPM is
pluggable, while currently one has to reflash firmware along with
switching TPM device.
