[PATCH v4 01/33] target/alpha: Tidy up alpha_cpu_class_by_name()

[Gavin Shan <gshan@redhat.com>]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

For target/alpha, the default CPU model name is "ev67". The default
CPU model is used when no matching CPU model is found. The conditions
to fall back to the default CPU model can be combined so that the code
looks a bit simplified.
