target/ppc/spapr_caps: Add macro to generate spapr_caps migration vmstate

Browse Source 
The vmstate description and the contained needed function for migration
of spapr_caps is the same for each cap, with the name of the cap
substituted. As such introduce a macro to allow for easier generation of
these.

Convert the three existing spapr_caps (htm, vsx, and dfp) to use this
macro.
