The clkctrl functions were becoming a mess. Normalise the names,
get rid of the xtal derived as special case and use the same
interface.

A number of pins on the imx233 are standard and manually calling
functions to acquire, set function/drive/output is painful. This
will become unmanageable when we will add support for the other
stmp chips.
Introduce the concept of virtual pin which is a way to completely
describe a virtual pin (virtual because pins are muxed).

The current pinctrl functions were a mess. Normalise the functions
names to make them shorter and clearer.

The SD SWITCH command has a result and can take a long time to
finish. Ignoring the answer and waiting an arbitrary time is
unreliable at best.

Register set selection is based on the value of the
IMX233_SUBTARGET value. The reg-select.h file (used by the
generated headers), does the selection based on this value as
follows:
- 3600 <= . < 3700: stmp3600 register set
- 3700 <= . < 3780: stmp3700 register set
- 3780 <= .: imx233 register set
Note that this selector relies on the name of the socs in the
register description to be respectively stmp3600, stmp3700 and
imx233.

This causes data_abort_handler from lib/unwarminder/safe_read.S to be
used instead. It allows unwarminder to avoid data aborts when
displaying the backtrace. A data_abort_handler remains in system-arm.c,
but it is not used because it is declared as a weak symbol.

This speeds up partial updates quite a bit but what is more
important it opens up a way to efficiently implement
lcd_blit_yuv() using hw colorspace conversion.

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.

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
Tested on iPod Photo.

* 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
pcm_sw_volume.h.
Simply use the software volume control for the SIM volume control
rather than the SDL volume control when the target would have it
natively.

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.
