Subject: [PATCH] Asoc: alc897: EAPD pin47 cannot work.

Due to unknown reason that snd_hda_intel would disable codec
wakeup twice during snd_hda_intel initialization, Internal SPK is forbidden
to put sound outside with snd_hda_intel driver on Unis B760 sku machine.
PIN47 EAPD status need be pulled down to work normally.
