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).
