[Qemu-trivial] [PATCH 0/3] tpm: add stubs to fix compiling with --disable-tpm

[Philippe Mathieu-Daudé]

This fixes building with --disable-tpm as reported by Zoltan:
  http://lists.nongnu.org/archive/html/qemu-devel/2017-10/msg05369.html

Cc'ing Peter in case this enters as build fix instead of via trivial.

Regards,

Phil.
