54bcca2973 sound: Add an ACPI driver for Maxim MAX98357ac
This chip is used on coral and we need to generate ACPI tables for sound
to make it work. Add a driver that does just this (i.e. at present does
not actually support playing sound).

2ca471379b sound: Add support for Intel HDA
The Intel High-definition Audio is a newer-generation audio system which
provides for transfer of a large number of audio stream, each containing
up to 16 channels.

Add support for HDA as a library which can be used by other drivers.
U-Boot currently uses only two channels (stereo).
