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.
