[RFC PATCH 03/10] target/ppc: Improve SPR indirect registers

SPRC/SPRD were recently added to all BookS CPUs supported, but they are only tested on POWER9 and POWER10, so restrict them to those CPUs. SPR indirect scratch registers presently replicated per-CPU like SMT SPRs, but the PnvCore is a better place for them since they are restricted to P9/P10. Als
