[PATCH v4 3/5] target/ppc: move SPR R/W callbacks to translate.c

["Bruno Larsen (billionai)" <bruno.larsen@eldorado.org.br>]

Moved all read and write callbacks for SPRs away from
translate_init.c.inc and into translate.c; these functions are
TCG only, so this motion is required to enable building with
the flag disable-tcg
