Arnd, thanks.

I squashed this to the associated commit.

I also fine-tuned the commit messages a bit (tag, imperative form).

Started also wondering tha tpm_ftpm_tee is a too generic name given that
this is for ARM TZ only. Would it make sense to rename it as something
like tpm_ftpm_tee_arm? Other proposals are welcome. Just made something
up.
