[ALSA] ice1724.c: toggle "chip reset" and "eeprom based setup" sequence
Let "chip reset" become first. Increasement of the "chip reset" related timeout leads to correctly read eeprom's contents here. Signed-off-by: Karsten Wiese <fzu@wemgehoertderstaat.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
