like I440FX by moving the condition into qemuDomainMachineHasBuiltinIDE
and adding more machines.
Reference: http://bugs.debian.org/805189
Verified on libvirt-1.3.1-1.el7.x86_64
Steps
start guest with I440FX machine type and 2 ide controller
<os>
<type arch='x86_64' machine='pc-i440fx-rhel7.2.0'>hvm</type>

<controller type='ide' index='0'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/>
</controller>
<controller type='ide' index='1'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
</controller>
