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.
