[PATCH] don't allow PMAC_APM_EMU for 64-bit

[Johannes Berg]

In b302887854d6f0c6f9fc3f1080535e7c1bd53134 I switched the apm emulation
code to use the generic code but accidentally dropped the PPC32
dependency from the configuration symbol. This adds it back.

Of course, selecting it on 64 bit doesn't make sense (no portables with
64-bit and PMU) and doesn't build either.
