vt-doc: Remove note about exceeding 255 vCPUs (#1789)

Starting with libvirt 10.10.0, an iommu and ioapic are configured automatically if needed, e.g. when configuring a VM with >255 vCPUs. Remove the note about needing to add the configuration manually. Signed-off-by: Jim Fehlig <[email protected]>

-          With &kvm;, it is possible to define a &vmguest; with more than 255
-          CPUs. However, additional configuration is necessary to start and run
-          the &vmguest;. The <literal>ioapic</literal> feature needs to be
-          tuned and an IOMMU device needs to be added to the &vmguest;. Below
-          is an example configuration for 288 CPUs.
