ALSA: emu10k1: Simplify firmware loader code
The EMU1010 support in emu10k1 driver has two request_firmware() calls, one for the main board and one for the dock. Both call patterns are fairly similar, and we can simplify it by introducing a helper function and a table instead of the open switch/case. Signed-off-by: Takashi Iwai <tiwai@suse.de>
