sparc: move adhoc CPUSPARCState initialization to realize time

Browse Source 
SPARCCPU::env was initialized from previously set properties
(with help of sparc_cpu_parse_features) in cpu_sparc_register().
However there is not reason to keep it there as this task is
typically done at realize time. So move post properties
initialization into sparc_cpu_realizefn, which brings
cpu_sparc_init() closer to cpu_generic_init().
