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.

The chip selection was relying only on DT. It was not possible to use the
driver without DT.
This adds the chip type detection from the I2C name, which
allows to use the driver from the platform driver without DT.

The driver did not have a mute function. The amplifier was brought out of
shutdown mode (hard-mute) once for ever in probe(), which was causing
clicks and pops when altering the I2C register configuration later.
This adds the digital_mute() function. The amplifier unmute in probe()
was removed.

The dapm field of the snd_soc_codec struct is eventually going to be
removed, in preparation for this replace all manual access to
codec->dapm.bias_level with snd_soc_codec_get_bias_level().

of_match_device() checks if dev->of_node is NULL, so we don't need to do
it again in the probe function.

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.
