vt-d: Better restrict memory ranges considered to be in Xen

The current implementation of xen_in_range() misses several memory
ranges that are used by the hypervisor and thus shouldn't get mapped
into dom0's VT-d tables.  This patch should make the check complete.

This patch is only against x86 because I'm not familiar enough with
IA64 to know how much, if any, of these checks apply there.
