ALSA: fix section for sa11xx-uda1341 platform driver

Don't use __init but __devinit to define probe function.  A pointer to
sa11xx_uda1341_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_SA11XX_UDA1341=m the following
probably oopses:

	echo -n sa11xx_uda1341.1 > /sys/bus/platform/driver/sa11xx_uda1341/unbind
	echo -n sa11xx_uda1341.1 > /sys/bus/platform/driver/sa11xx_uda1341/bind
