Yeah, we need a design decision here. What I care is that they should
be in the same subsystem. I did trusted keys directly to TPM 2.0 subsys
because the subsystem was not too robust back then.

Right now I think it would be feasible to implement TPM2 trusted keys
outside TPM driver since the whole transmit functionality is way more
robust.
