ppc: pnv: use generic cpu_model parsing

Browse source 
use common cpu_model prasing in vl.c and set default cpu_model
using generic MachineClass::default_cpu_type.

Beside of switching to generic infrastructure it solves several
issues.

 * ppc_cpu_class_by_name() is used to deal with lower/upper case
   and alias translations into actual cpu type, which fixes
    '-M powernv -cpu power8' and '-M powernv -cpu power9_v1.0'
   usecases which error out with:
    'invalid CPU model 'FOO' for powernv machine'
 * allows to switch to lower-case typenames in pnv chip/core name
   (by convention typnames should be lower-case)
 * replace aliased names /power8, power9, .../ with exact cpu model
   names (i.e. typenames should be stable but aliases might decide to
   point to other cpu model withi family or changed by kvm). It will
   also help to simplify pnv_chip/core code and get rid of dependency
   on cpu_model parsing.
