ppc: replace inter-function cyclic dependency/recurssion with 2 simple lookups 

previous patches cleaned up cpu model/alias naming which
allows to simplify cpu model/alias to cpu type lookup a bit
byt removing recurssion and dependency of ppc_cpu_class_by_name() /
ppc_cpu_class_by_alias() on each other.
Besides of simplifying code it reduces it by ~15LOC.
