POWERPC: Fix build of modular drivers/macintosh/apm_emu.c

upstream commit: 620a2459

Currently, if drivers/macintosh/apm_emu is a module and the config
doesn't have CONFIG_SUSPEND we get:

ERROR: "pmu_batteries" [drivers/macintosh/apm_emu.ko] undefined!
ERROR: "pmu_battery_count" [drivers/macintosh/apm_emu.ko] undefined!
ERROR: "pmu_power_flags" [drivers/macintosh/apm_emu.ko] undefined!

on PPC32.  The variables aren't wrapped in '#if defined(CONFIG_SUSPEND)'
so we probably shouldn't wrap the exports either.  This removes the
CONFIG_SUSPEND part of the export, which fixes compilation on ppc32.
