[Xen-changelog] Test suspend and resume cycles of the TPM front- and backend.

[Xen patchbot -unstable <patchbot-unstable@xxxxxxxxxxxxxxxxxxx>]

# HG changeset patch
# User emellor@xxxxxxxxxxxxxxxxxxxxxx
# Node ID e36f95b43bf1c3e04eea31d10db5bb2d0db6eefe
# Parent  b78cab886a1e12b7c75e9623b4c4f8b3da2a6525
Test suspend and resume cycles of the TPM front- and backend.
Now that sysfs is mounted in the RAM disk of the test environment, the
test code does not need to do this anymore. This patch also simplifies
previous tests and the APIs used there. If prerequisites are not met
(vtpm manager not running) the patch will 'skip'.
