x86: sound: Add sound support for samus (broadwell)
Add a sound driver for samus which ties together the audio codec and
I2S controller.
For now broadwell_sound is commented out in the makefile since we cannot
compile it without sound support enabled. The next commit fixes this.

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).

sound: Add uclass operations for beeping
Some audio codecs such as Intel HDA do not need to use digital data to
play sounds, but instead have a way to emit beeps. Add this interface as
an option. If the beep interface is not supported, then the sound uclass
falls back to the I2S interface.

dm: sound: Use the correct number of channels for sound
At present the 'beep' sound generates a waveform for only one channel even
if two are being used. This means that the beep is twice the frequency it
should be. Correct this by making it a parameter.
The fix in a previous commit was correct for sandbox but not for other
boards.
