with features converted to properties we can reuse shared
with x86 cpu_legacy_parse_featurestr() for features parsing
and drop legacy parser that manipulated CPU directly.

With that in place and sparc_cpu_parse_features() providing
generic CPUClass::parse_features callback, the cpu_sparc_init()
will do the same job as cpu_generic_init() so replace content
of cpu_sparc_init() with it.

v2:
  * use new cpu_legacy_parse_featurestr() without
    plus_features/minus_features
  * drop cpu_legacy_apply_features() as it's been removed in
    previuos patch and new cpu_legacy_parse_featurestr()
    does its job
