Subject: [PATCH v2] ALSA: hda: Add TAS2770 support

Add TAS2770 support in TI's HDA driver. And add hda_chip_id for
more products. Distinguish DSP and non-DSP in firmware
loading function.

Signed-off-by: Baojun Xu <baojun.xu@...com>

---
v2:
 - Rewrite the patch description
 - Move registers define for TAS2770 from tas2781.h to tas2770-tlv.h
 - Add new chip ID define for HDA
 - Add digital volume control in tas2770_snd_controls
 - Change public kcontrol name from tas27xx_ to tasdevice_
 - Create new function for kcontrol adding
 - Create new function for DSP binary loading
 - Rename chip_id to hda_chip_id in i2c_probe for the supported devices
