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).

+ Most Intel chips have an HDA (High-definition audio) codec which can
+ be used by U-Boot to play simple beeps. This is also sometimes called
+ Azalia which was the development code-name. It requires setup
+ information in the device tree (see intel-hda.txt).
