Commit 0f8445820f11a69154309863960328dda3dc1ad4 'xen: piix reuse pci
generic class init function' already resolved redundant code which in
turn rendered piix3-ide-xen redundant.

Creating a guest and migrating a guest seems to work fine without
"piix3-ide-xen", and I can't find this name used outside of QEMU. So I
guess it's fine to remove it.
