PowerPC pseries based VMs do not support a floppy disk controller.
This prohibits libvirt from adding floppy disk for a PowerPC pseries VM.

The architecture and machine type do not affect parsing of the disk.
If we really want to forbid even parsing a domain with a floppy,
this would better be done somewhere in the virDomainDefPostParse
functions.
But I think we should happily parse this domain and only report an error
on startup, so all the domain_conf.c changes can be dropped.

The rest looks good.
