This is a port of the sound/oss/sh_dac_audio.c driver. The driver uses an on-chip 8-bit D/A converter, which has a speaker connected to one of its channels, found in several ancient HP machines. For interrupts it uses a high-resolution timer (hrtimer). Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx).
Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver would be obsolete soon, and it could be removed.
Changes since V3:
- renamed sound/sh/snd_sh_dac_audio.c to sound/sh/sh_dac_audio.c
Changes since V2:
- renamed include/sound/dac_audio.h to include/sound/sh_dac_audio.h
Changes since V1:
- moved the platform device code into board code.
- dropped dac_audio_sync(), since that code is not needed (it was inherited of the old oss driver).
- rewrote the code with style problems.
