Main source code for tas2781 driver for SPI.

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

---
v2:
 - Update information in file header of tas2781-spi.h.
 - Remove useless micro define.
 - Change TASDEVICE_I2CChecksum to TASDEVICE_Checksum
 - Remove enum control_bus as current code support SPI only.
 - Remove device define as current code support TAS2781 only.
 - Remove spi_device **spi_devs in structure tasdevice_priv.
 - Remove cal_binaryname in structure tasdevice_priv.
 - Remove ndev in structure tasdevice_priv.
 - Change isacpi and  isspi, replace by control_bus(I2C or SPI).
 - Remove void tasdevice_spi_dsp_remove(void *context).
 - Add acpi_device and irq in structure tas2781_hda in tas2781_hda_spi.c.
 - Remove parameter chn in all of registers access functions.
 - Add tascodec_spi_init().
 - Add chip select gpio set for SPI device.
 - Change tasdevice_tuning_switch() to tasdevice_spi_tuning_switch().
 - Change device offset from tas_priv->ndev to tas_priv->index.
 - Change tasdevice_dsp_remove() to tasdevice_spi_dsp_remove().
 - tasdevice_prmg_load() to tasdevice_spi_prmg_load().
 - Change tasdevice_config_info_remove() to
   tasdevice_spi_config_info_remove().
 - Add one dummy byte shift when read from page 2~127, or not book 0.
 - Change tasdevice_spi_change_chn_book() to tasdevice_spi_switch_book()
 - Perform put_device(physdev) before error return.
 - Change calibration data id to 2781 from 2783 in EFI
 - Change calibration data structure name in comments.
