rockbox/firmware/export/wm8978.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.

Gigabeat S/i.MX31/wm8978: Clean up clocking information in the general wmcodec/pcm drivers and move it to the target's wmcodec/i2s files.

Gigabeat S: Fully enable access to hardware tone controls and 3-D effect feature. Under the hood, it's designated a hardware equalizer since it is one. Implement code framework for hardware EQ in general. Menu aspect is well abstracted and so the UI and strings can be changed around if taste doesn't quite suit. So far the emphasis is distinction of the UI labelling from the software EQ so that it's clear the settings are for a different thing.

wm8978: Clean out silly macros. Use 'POS' convention instead for shifted bitfields. Additionally, use volume update latching for all volume settings.

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

Gigabeat S: Allow recording from FM. Give FM the same volume range as playback. NOTE: This bumps the si4700 output volume to -0dB so other players with that may need a minor adjustment.

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

FS#9609 FM radio support for the Gigabeat S, seeking/scanning is not yet

implemented but manual tuning works nicely. Thanks to Rafaël Carré,
Bertrik Sikken and Robert Menes for suggestions and debugging help.
