Olaf Hering e120e8d03a [POWERPC] Fix undefined reference to device_power_up/resume 
Current Linus tree fails to link on pmac32:

drivers/built-in.o: In function `pmac_wakeup_devices':
via-pmu.c:(.text+0x5bab4): undefined reference to `device_power_up'
via-pmu.c:(.text+0x5bb08): undefined reference to `device_resume'
drivers/built-in.o: In function `pmac_suspend_devices':
via-pmu.c:(.text+0x5c260): undefined reference to `device_power_down'
via-pmu.c:(.text+0x5c27c): undefined reference to `device_resume'
make[1]: *** [.tmp_vmlinux1] Error 1

changing CONFIG_PM > CONFIG_PM_SLEEP leads to:

drivers/built-in.o: In function `pmu_led_set':
via-pmu-led.c:(.text+0x5cdca): undefined reference to `pmu_sys_suspended'
via-pmu-led.c:(.text+0x5cdce): undefined reference to `pmu_sys_suspended'
drivers/built-in.o: In function `pmu_req_done':
via-pmu-led.c:(.text+0x5ce3e): undefined reference to `pmu_sys_suspended'
via-pmu-led.c:(.text+0x5ce42): undefined reference to `pmu_sys_suspended'
drivers/built-in.o: In function `adb_init':
(.init.text+0x4c5c): undefined reference to `pmu_register_sleep_notifier'
make[1]: *** [.tmp_vmlinux1] Error 1

So change even more places from PM to PM_SLEEP to allow linking.
