moxie: fix qemu-system-moxie failing to start with CLI "-cpu MoxieLite"

It 'works' with default CPU only because of bug in
moxie_cpu_class_by_name() where it treats cpu_model
as type name and default cpu_model also happens to be
type name. But specifying explicitly cpu on CLI,
ex: '-cpu MoxieLite', makes QEMU fail since
moxie_cpu_class_by_name() doesn't traslate cpu_model
to cpu type and fails to find corresponding object class.

Fix moxie_cpu_class_by_name() to do proper
   cpu_model -> cpu type
translation and fix default cpu_model to be cpu_model
instead of being typename.
