rockbox/firmware/export/wm8731.h, branch working

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.

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.

cleanup audiohw_set_frequency by adding it to audiohw.h and removing it from all driver .h files

Bring consistency to pcm implementation and samplerate handling. Less low-level duplication. A small test_sampr fix so it works on coldfire again.

Have drivers merged for WM8711/21/31 since they are so similar but respect all register differences between codecs. Change minis to #define the actual codec type. If anything breaks check if OSCPD and CLKOUTPD need to be clear for the target- H10 is fine. A nice naming convention suggestion for WM codec multidrivers would be welcome rather than naming for a specific chip.

Simplify the wm8731 driver by adding a masked write function. Change _write_or/and to _set/clear. Reduce init sequence by initializing shadows to hardware defaults.

Remove the audiohw_set_nsorder() function since it is not used, only implemented on WM8731 and not wanted/used there.
