4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kailang Yang <kailang@realtek.com>

commit ea04a1dbf8b1d6af759d58e705636fde48583f8f upstream.

Fill COEF to change EAPD to verb control.
Assigned codec type.

This is an additional fix over 92f974df3460 ("ALSA: hda/realtek - New
vendor ID for ALC233").

[ More notes:
  according to Kailang, the chip is 10ec:0235 bonding for ALC233b,
  which is equivalent with ALC255.  It's only used for Lenovo.
  The chip needs no alc_process_coef_fw() for headset unlike ALC255. ]
