[PULL 12/42] target/ppc: used ternary operator when registering MAS

[David Gibson]

From: "Bruno Larsen (billionai)" <bruno.larsen@eldorado.org.br>

The write calback decision when registering the MAS SPR has been turned
into a ternary operation, rather than an if-then-else block.

This was done because when building without TCG, even though the
compiler will optimize away the pointers to spr_write_generic*, it
doesn't optimize away the decision and assignment to the local pointer,
creating compiler errors. This cleanup looked better than using ifdefs,
so  we decided to with it.
