Looking at the detected versions and the qemu code it seems that
'intremap' is supported for all qemu versions and also it doesn't seem
to be able to be disabled.
Thus this capabilit should not be needed as you can assume it's always
present.
It is pointless checking for any of these capabilities since the
device today is unusable AFAICT, so even if the feature has existed
for years, we won't want to use it. Once the PCI integration is fixed,
we will merely need 1 capability check to detect the fixed design and
everything prior to that point will be implied.
With regards,
Daniel
