Conversion from centibels to register values was left out of

Credit goes to Dave Marsh for providing the fix.
Just another little oversight from sound/audiohw rework.

Just one more SNAFU after redoing sound.c. Software bass/treble controls
in the DSP expect .1 dB gain increments but the gains were being set as
1 dB increments because that's what the AUDIOHW_SETTING specifies. Just
x10 the gains given to audiohw_set_bass/treble.

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.

If AUDIOHW_CAPS is defined without explicit BASS_CAP/TREBLE_CAP while
HAVE_SW_TONE_CONTROLS is defined, AUDIOHW_HAVE_BASS/TREBLE should be
defined or otherwise the tone controls won't show up. TREBLE/BASS were
being defined if AUDIOHW_CAPS was NOT defined, but the same rule should
apply if the codec needs to specify other caps but doesn't use hardware
tone controls.
(I'm surprised noone noticed some settings gone missing :-)

Based on FS#9920 by Ryan Press with changes to selection logic so
that it works on my iPod Photo. Should also work on iPod Color/4G
and Mini2G. Moved all target specific code from
firmware/drivers/serial.c into new file
firmware/target/arm/pp/uart-pp.c in the same manner as other
target specific uart code.
Update to fix build error on ipodmini2g by adding defines in config file.
Removed unwanted whitespace

* 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.

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.

Onda VX747 sim was missing a limits #define; #include limits.h in

Simply use the software volume control for the SIM volume control

Implements double-buffered volume, balance and prescaling control in
the main PCM driver when HAVE_SW_VOLUME_CONTROL is defined ensuring
that all PCM is volume controlled and level changes are low in latency.
Supports -73 to +6 dB using a 15-bit factor so that no large-integer
math is needed.
Low-level hardware drivers do not have to implement it themselves but
parameters can be changed (currently defined in pcm-internal.h) to work
best with a particular SoC or to provide different volume ranges.
Volume and prescale calls should be made in the codec driver. It should
appear as a normal hardware interface. PCM volume calls expect .1 dB
units.

In the modern everything-can-be-skinned world, themes are beginning
to hit the limit of 8 fonts (which includes sysfont). Increasing this
to 12 will allow some headroom, at the cost of a bit more RAM usage
(about 20 bytes per extra possible font, so about 80 bytes total here)

The old way actually mis-used the API (I misunderstood the docs) because
it specified the marker position as a "low buffer watermark" but instead of a
future playback head position.
The replacement is a simple thread that writes the data regardless of the
filling level of the buffer (write() will just block) and polls the playback
state periodically.

This was spotted while playing with qemu-jz:
1) rockbox reads TECR and TESR which are described as write-only
registers. Datasheet doesn't mention what happens if they are
readed. Apparently this doesn't have fatal side effects.
It comes down to two defines from jz4740.h
__tcu_stop_counter(n) and __tcu_start_counter(n) which use
read-modify-write sequence.
2) rockbox accesses out of bound offset 0xd4 in DMA memspace.
It comes from dis_irq() in system-jz4740.c. NUM_DMA is 6 but
DMA channels are 0-5 so (irq <= IRQ_DMA_0 + NUM_DMA)) bound
check is wrong.
This are *NOT* tested on device.
