Subject: [PATCH v7 1/1] ALSA: hda/tas2781: Add tas2781 hda driver based on SPI

Integrate tas2781 hda spi driver configs for HP (Varcolac).
Every tas2781 SPI node was added by serial-multi-instantie.c as a single
SPI device. The code support Realtek as the primary codec.

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

---
v7:
 - Add new project Gemtree (0x103c8daa) support for tas2781 spi driver.
v6:
 - Remove client in tasdevice_priv struct as it was not used.
 - Change format for tasdevice_spi_dev_write() in tas2781_hda_spi.c.
 - Change update bits function to read & write mode, as tas2781 use last bit
   to mask read & write, it cause regmap_update_bits work not as our expected.
 - Add element in tas2781_snd_controls, tas2781_prof_ctrl,
   tas2781_dsp_conf_ctrl, to support second device.
