ASoC: tas571x: add input channel mixer for TAS5717/19

Add channel 1 and 2 input mixer registers and the related ALSA mixer
controls for TAS5717/19 chips.

The mixer control coefficients on the chip are linear in the range
-3.99999 to +3.99999, encoded in 3.23 number format.
In this patch the mixer controls are limited to 128 values
from 0.0 to 1.0 in 1/64 steps.

ASoC: tas571x: added missing register literals

The list of TAS571x registers was incomplete.
Added the missing register definitions up to the register 0x25.
Added volatile and read-only register tables into tas5711_regmap_config
and tas5717_regmap_config.

The chip has 256 registers in total. But from address 0x29 on
(0x26 to 0x28 are reserved) the register width varies between
20, 12 and 8 bytes, which the register map cannot represent.

ASoC: tas571x: New driver for TI TAS571x power amplifiers

Introduce a new codec driver for the Texas Instruments
TAS5711/TAS5717/TAS5719 power amplifier chips. These chips are typically
used to take an I2S digital audio input and drive 10-20W into a pair of
speakers.
