Add finer granularity to start command: now commands can be
prepared, schedule and semaphore increased independently.

Factorise pin setup, rewrite PIO code, add support for lcdif irq,
handle all the various differences between the stmps, drop yuv
blitting code since it already exists in the common lcd drivers.

The lradc architecture of the stmp3600 is rather different:
only channels 6 and 7 have configurable source and we need to
take care when allocating channels so that we can actually
measure the right channel! Delegate die temperature sensing to
the power block on stmp3600.

There are many small differences between them. In particular
some regulators are not available on stmp3600. Also the vbusvalid
detect method is not available as an irq on stmp3600 and seems
broken on stmp3700. Finally die temperature is handled by the
power block on stmp3600.

Under some circumstance (timeout), the dma interrupt is not fired
and only the error one is. This can happen with some picky SD
cards and with the current code it causes a 1 second timeout.
This code properly catches the error interrupt to stop as soon
as possible.

The current pwm interface is too low-level. Introduce a higher
level setup function which directly computes the parameters from
the required frequency.

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 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.

Eliminates the pcmrec thread and keeps playback and recording engine
operation mutually-exclusive.
audio_thread.c contains the audio thread which branches to the
correct engine depending upon the request. It also handles the main
audio initialization.
Moves pcm_init into main.c just before dsp_init because I don't want
that one in audio_init in the new file.
(Also makes revision df6e1bc pointless ;)

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.

If target has HW tone controls but no HW prescaler (non-implemented or
non-existent), audiohw_set_prescaler() should, for now, do nothing.

It can cause excessively long interrupt outages if moving a larger
buffer and disrupt audio where DMA is not at a higher interrupt priority
such as FIQ.
Some targets, like Gigabeat S, have very low audio interrupt latency
requirements and will even channel swap if they are missed. Pictureflow
will make the issue very obvious. Even then, moves could take
milliseconds or more depending on the buffer size which is far too long
for any target.

Letting go of the button before the host is detected allows storage mode
to be entered even though a button was down when plugging. Sometimes the
host would try several times and the button would have to be held down
for several seconds to avoid a storage connection.
The adjustment wasn't made when switching to setup request host
detection.
