ALSA: ice1712: Add Wolfson Microelectronics WM8776 codec support
Needed by Philips PSC724 subdriver. The code does not contain any card-specific bits so other ice17xx cards using this codec could be converted to use this generic code. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
