x86/hvm: don't pass through port 0x80 in a few special cases

In a recent commit (99f85a28a78e96d28907fe036e1671a218fee597), KVM
disabled the passthrough of this port due to known problems on certain
HP laptops (see
http://lkml.indiana.edu/hypermail/linux/kernel/0712.3/0872.html
and http://lkml.indiana.edu/hypermail/linux/kernel/0801.0/2388.html).

For Xen, don't do this globally, but rather based on a DMI black list.
