reset must occur after we defined the CPU features.

7dbe11acd8 Handle all MMU models in switches, even if it's just to abort because of lack

  on those processors.

e1833e1f96 Rework PowerPC exceptions model to make it more versatile:
* don't use exception vectors as the exception number.
  Use vectors numbers as defined in the PowerPC embedded specification instead
  and extend this model to cover all emulated PowerPC variants exceptions.
* add some missing exceptions definitions, from PowerPC 2.04 specification
  and actual PowerPC implementations.
* add code provision for hypervisor exceptions handling.
* define exception vectors and prefix in CPUPPCState to emulate BookE exception
  vectors without any hacks.
* define per CPU model valid exception vectors.
* handle all known exceptions in user-mode only emulations.
* fix hardware interrupts priorities in most cases.
* change RET_EXCP macros name into GEN_EXCP as they don't return.
* do not stop translation on most instructions that are not defined as
  context-synchronizing in PowerPC specification.
* fix PowerPC 64 jump targets and link register update when in 32 bits mode.
* Fix PowerPC 464 and 464F definitions.
