powerpc/windfarm: Add detection for second cpu pump

commit 529586dc39b0ec47c6290c4e7bed6ea3ffd1d8fb upstream.

Windfarm SMU control is explicitly missing support for a second CPU pump in G5 PowerMacs. Such machines actually exist  (specifically Quads with a second pump), so this patch adds detection for it.
