Update trusted key documentation with additional comparisons between
discrete TPMs and TEE.

Isn't this additional comparison limited to a particular type of TPM
(discrete TPMs) and ignored other TPM implementations (virtual TPM,
firmware TPM etc.)? I think your later comment about on-chip versus
off-chip points at these missing pieces as well.

I would rather suggest comparing TPM and TEE on the basis of
interfaces and implementation guidelines provided by corresponding
standards as I think this is the most relevant part to the kernel.

I agree with this point of view.

I'm also finding hard to understand the reason for the thread model
documentation, i.e. how it connects to the implementation.
