Thomas Huth a716766889 hw/ppc: Remove the deprecated spapr-pci-vfio-host-bridge device 
It's a deprecated dummy device since QEMU v2.6.0. That should have
been enough time to allow the users to update their scripts in case
they still use it, so let's remove this legacy code now.

# Purposes of the following whitelist:
# * Avoiding verbose log messages when we find known non-fatal
# (exitcode=1) errors
# * Avoiding fatal errors when we find known crashes
# * Skipping machines/devices that are known not to work out of
# the box, when running in --quick mode
#
# Keeping the whitelist updated is desirable, but not required,
# because unexpected cases where QEMU exits with exitcode=1 will
# just trigger a INFO message.
# Valid whitelist entry keys:
# * accel: regexp, full match only
# * machine: regexp, full match only
# * device: regexp, full match only
# * log: regexp, partial match allowed
# * exitcode: if not present, defaults to 1. If None, matches any exitcode
# * warn: if True, matching failures will be logged as warnings
# * expected: if True, QEMU is expected to always fail every time
# when testing the corresponding test case
# * loglevel: log level of log output when there's a match.
