[libvirt] [PATCH V3 23/24] src/xenxs:Refactor code formating emulated devices config

From: Kiarie Kahurani <davidkiarie4(a)gmail.com&gt; introduce function xenFormatXMEmulatedHardware(virConfPtr conf,....); which formats emulated hardware config instead signed-off-by: David Kiarie&lt;davidkiarie4(a)gmail.com&gt;
