The x86 side is mostly self contained, so the damage there is minimal,
but the TPM parts are changing the generic operations and the x86 parts
depend on them.

So let's not create a chicken and egg problem and solve the TPM parts,
which at my cursory glance are partially legitimate fixes, independent
of the actual trenchboot x86 functionality.
