Straighten out the mad twisted state of sound.c and related areas. This is going right in since it's long overdue. If anything is goofed, drop me a line or just tweak it yourself if you know what's wrong. :-) Make HW/SW codec interface more uniform when emulating HW functionality on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to- DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX" APIs are all in sound.c with none in DSP code any longer. Reduce number of settings definitions needed by each codec by providing defaults for common ones like balance, channels and SW tone controls. Remove need for separate SIM code and tables and add virtual codec header for hosted targets. Change-Id: I3f23702bca054fc9bda40f49824ce681bb7f777b

#ifndef HOSTED_CODEC_H
#define HOSTED_CODEC_H
Provide high resolution volume and prescaler to hosted targets. HAVE_SW_VOLUME_CONTROL is required and at this time only affects the SDL targets using pcm-sdl.c. Enables balance control in SDL targets, unless mono volume is in use. Compiles software volume control as unbuffered when PCM_SW_VOLUME_UNBUFFERED is defined. This avoids the overhead and extra latency introduced by the double buffer when it is not needed. Use this config when the target's PCM driver is buffered and sufficient latency exists to perform safely the volume scaling. Simulated targets that are double-buffered when made as native targets remain so in the sim in order to run the same code.

#define AUDIOHW_CAPS (MONO_VOL_CAP)
Do some cleanup, adjustment and a couple fixes to recent sound changes. * SOUND_x enum can be generated by audiohw_settings.h along with settings entries and sound_val2phys. * VOLUME_MIN and VOLUME_MAX are no longer necessary within sound.c. If you need them, they are for target-defined purposes. * Fix up SDL volume implementation in sdl.c. Move sim volume calculation code to pcm-sdl.c. * Min trigger tresholds were based upon VOLUME_MIN for some reason. These setting have nothing to do with playback volume. Since it is no longer present, set these at -89dB which is the minimum peak meter sensitivity setting. * Fix an oversight in wm8758.c. I forgot to add the dB->register conversion to audiohw_set_volume. Change-Id: Ie1df33f1793eee75e6793f16bc7bddd16edb7f75
