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.

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.
   Previous version add sound card for first index only.

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.
   Previous version add sound card for first index only.
 - Change calibration registers address declaire to TASDEVICE_REG() mode.
 - Add snd_ctl_new1() for second device.
 - Change format for tas2781_hda_unbind() to fit 79 chars in one line.
 - Remove client for spi as it was not used.
 - Remove unused variables.
 - Remove cur_prog clean in runtime_suspend().
 - Remove unused variables.
 - Add tasdevice_spi_tuning_switch() in runtime_resume.
 - Remove cur_prog clean in system_resume().
 - Add tuning switch if playback started in system_resume().
 - Change TASDEVICE_PAGE_REG to TASDEVICE_REG_ID in tas2781_spi_fwlib.c.
 - Remove calibration binary load functions as data will be loaded from EFI.

 - Remove old hardware id "TIAS2781" as no production on market.
 - Change max page size to 256 in tas2781-spi.h.

 - Add registers default table into structure regmap_config.
 - Change parameter from book number to whole register address.
 - Remove page 0 switch as SPI driver will do it.
 - Add bit(0) for read function as tas2781 will check last bit of address,
   to determine operation mode is read (1) or write (0).
 - Change switch case to if check in tas2781_hda_playback_hook(),
   as it may cause compile problem in clang-19 building.
 - Change variable declaration position.
 - Change order in if check.
 - Remove old hardware id ("TIAS2781") support.
