target-arm: Replace wildcarded cpreg definitions with precise ones for ARMv8
Many of the reginfo definitions in cp_reginfo[] use CP_ANY wildcards. This is for a combination of reasons: * early ARM implementations really did underdecode * earlier versions of QEMU underdecoded and we can't tighten this up because we don't know if guests really require this or not * implementation convenience For ARMv8 the architecture has tightened things up and system and coprocessor registers are always specifically decoded. We take advantage of this opportunity for a clean break by restricting our CP_ANY wildcarded reginfo to pre-v8 CPUs, and providing specifically decoded versions where necessary for v8 CPUs.
