Turn the *-user macro into a no-op inline function to avoid
unused-variable warnings and band-aiding #ifdef'ery.

This allows to drop an #ifdef for alpha and avoids more for unicore32
and other upcoming trivial realizefn implementations.

This generalizes {ARM,M68k,Alpha}CPUListState to avoid declaring it for
each target. Place it in cpu-common.h to avoid circular dependencies.

Make TYPE_ALPHA_CPU abstract and add types <name>-alpha-cpu.
Use type inheritence, and turn "2*" models into aliases.

Move cpu_alpha_init() to cpu.c and split out CPU realization.
Default to creating type "ev67-alpha-cpu" as before.
