ASoC: max98396: Implement DSP speaker monitor
Allow the selection of the TDM slot that is used to send back speaker
monitor data. The DT property adi,spkfb-slot-no can be used to configure
this setting which defaults to 2.

ASoC: max98396: Fix register access for PCM format settings
max98396_dai_set_fmt() modifes register 2041 and touches bits in the mask
0x3a. Make sure to use the right mask for that operation.

ASoC: max98396: Improve some error prints
Let's log what actually failed and log at some more places.

ASoC: max98396: add voltage regulators
The device has up to 5 potentially independent power supplies:
AVDD, DVDD, DVVDIO, VBAT and PVDD. The former 3 are mandatory for the
device to function. One of VBAT and PVDD should also be made available.

Regulators are enabled during probe time and will stay active except when in
suspend mode.

Futher, the chip needs to be informed about the presence of VBAT through a
bit in register 0x20a0.

ASoC: max98396: add amplifier driver
This series of patches adds support for Analog Devices MAX98396
mono amplifier with IV sense. The device provides a PCM interface
for audio data and a standard I2C interface for control data
communication. This driver also supports MAX98397 which is
a variant of MAX98396 with wide input supply range.
