Is there anything which is actually Xen specific about the driver in
tpm.[ch]? Would it be better to just probe for it, perhaps gates by a
Kconfig option which enables TPM support.

And following that train of thought I think you could reasonable drop
"4hvm" from the name. And possibly even the leading "v", since I suppose
seabios shouldn't really care if the tpm is emulated or real so long as
it looks like a real tpm.
