336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

02662480a8 sandbox: sound: Handle errors better in sound_beep()
At present an error does not stop the sound-output loop. This is incorrect
since nothing can be gained by trying to continue. Fix it.

3062cd17af sound: Add a new stop_play() method
At present there is no positive indication that U-Boot has finished
sending sound data. This means that it is not possible to power down an
audio codec, for example. Add a new method that is called once all sound
data has been sent.

Add a new method for this, called when the sound_play() call is done.

2850266965 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.

e65f9ef9f2 sound: Mark sound_setup() as optional
This method in the sound API is optional since some drivers can do this
when probing or as part of SoC init. Mark it as such.

f987177db9 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.

d490189865 dm: sound: Create a uclass for sound
The sound driver pulls together the audio codec and i2s drivers in order
to actually make sounds. It supports setup() and play() methods. The
sound_find_codec_i2s() function allows locating the linked codec and i2s
devices. They can be referred to from uclass-private data.

Add a uclass and a test for sound.
