ALSA: move snd_powermac's probe function to .devinit.text
A pointer to snd_pmac_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (when having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.
