[PATCH v4] ASoC: tas2781: Add tas2781 driver

[Shenghao Ding]

Create tas2781 driver.

Signed-off-by: Shenghao Ding <13916275206@xxxxxxx>

---
Changes in v4:
 - make the entire comment block a C++ one
 - remove uncessary dbg log in the firmware downlaoding
 - remove simliar macro already defined in ALSA header
 - use crc8_populate_msb() to generate the crc lookup table
 - remove all the hungarian notation in the code
 - remove log failures to allocate
 - add comment for tas2781_digital_getvol on the reason to custom
   control, tas2781 contain book and page two-level regmap,
   especially book switching will set two registers, one is
   BXXPXXR00, the other is B0P0R7F, after switching to the
   correct book, then the code can leverage the mechanism for
   paging, and access the register.
 - return 1 in all of the put control callback
 - fix "Control names for volumes should end with Volume"
 - remove the Lock in the control callback functions
 - remove likely() or unlikely().
 - remove uncessary GPIO check for irq
 - remove unused functions
 - remove i2c check in the i2c probe
