docs: Drop obsolete statement about CPU modes and migration

Browse Source 
The guest CPU definition has always been updated automatically during
migration. And currently we just transform any host-model CPU into a
custom one when a domain starts.

In both <code>host-model</code> and <code>host-passthrough</code>
mode, the real (approximate in <code>host-passthrough</code> mode) CPU
definition which would be used on current host can be determined by
specifying <code>VIR_DOMAIN_XML_UPDATE_CPU</code> flag when calling
<code>virDomainGetXMLDesc</code> API. When running a guest that might
be prone to operating system reactivation when presented with
different hardware, and which will be migrated between hosts with
different capabilities, you can use this output to rewrite XML to the
<code>custom</code> mode for more robust migration.
