ASoC: codecs: Add Awinic AW8738 audio amplifier driver
The Awinic AW8738 is a simple audio amplifier using a single GPIO.
The main difference to simple-amplifier is that there is a "one-wire
pulse control" that allows configuring the amplifier to one of a few
pre-defined modes. This can be used to configure the speaker-guard
function (primarily the power limit for the amplifier).
Add a simple driver that allows setting it up in the device tree
with a specified mode number.
