pseries: Correctly create ibm,segment-page-sizes property
The core tcg/kvm code for ppc64 now has at least the outline
capability to support pagesizes beyond the standard 4k and 16MB. The
CPUState is initialized with information advertising the available
pagesizes and their correct encodings, and under the right KVM setup
this will be populated with page sizes beyond the standard.
Obviously guests can't use the extra page sizes unless they know
they're present. For the pseries machine, at least, there is a
defined method for conveying exactly this information, the
"ibm-segment-page-sizes" property in the guest device tree.
This patch generates this property using the supported page size
information that's already in the CPUState.
