For now broadwell_sound is commented out in the makefile since we cannot compile it without sound support enabled. The next commit fixes this.

The testing works by checking the data that would be emitted. Add a device-tree property to silence the sound, and enable it for testing.

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

Add this interface as an option. If the beep interface is not supported, then the sound uclass falls back to the I2S interface.
