pseries: Support SMT systems for KVM Book3S-HV

Alex Graf has already made qemu support KVM for the pseries machine
when using the Book3S-PR KVM variant (which runs the guest in
usermode, emulating supervisor operations). This code allows gets us
very close to also working with KVM Book3S-HV (using the hypervisor...

At present, using the hypervisor aware Book3S-HV KVM will only work

capability, but they lack the VRMA feature which makes assigning guest

pseries: Use Book3S-HV TCE acceleration capabilities

The pseries machine of qemu implements the TCE mechanism used as a
virtual IOMMU for the PAPR defined virtual IO devices. Because the
PAPR spec only defines a small DMA address space, the guest VIO
drivers need to update TCE mappings very frequently - the virtual...
