ALSA: Fix section for snd-aica platform driver

Don't use __init but __devinit to define probe function.  A pointer to
snd_aica_probe is passed to the core via platform_driver_register and so the
function must not disappear after the module is loaded.  Using __init
and having HOTPLUG=y and SND_AICA=m the following probably oopses:

	echo -n AICA > /sys/bus/platform/driver/AICA/unbind
	echo -n AICA > /sys/bus/platform/driver/AICA/bind

Strange enough add_aicamixer_controls which is only called by
snd_aica_probe was already using __devinit.

While at it move the remove function to .devexit.text section.
