[Qemu-ppc] [QEMU-PPC] [PATCH V5 0/7] target/ppc: Rework spapr_caps

[Suraj Jitindar Singh]

The following patch series adds 3 new tristate capabilities and their
associated handling.

A new H-Call is implemented which a guest will use to query the 
requirement for and availability of workarounds for certain cpu 
behaviours.

Applies on top of David's tree: ppc-for-2.12

The main changes to V5 are:
- Add patch 2/7 to series to introduce macros to generate migration fields
- Fix bisect breakage in 3/7 due to unused function
- Use assert in 7/7 for invalid cap values
