In most devices, the button ladder is not actually derived from VDDIO but
from a constant voltage source, making it very easy to read it. However on
some devices like ther ZEN X-Fi Style, the ladder is wired to VDDIO we
can be changed so it's crucial that the button driver correctly scales the
values wrt VDDIO.

The hardware watchdog automatically shutdown the device after 10s of
inactivity, being defined as 10s without the tick IRQ fired (aka braindead
device).
The software IRQ mechanism is more interesting: it uses a very high priority
timer setup as one-shot to trigger after 5s of inactivity (but IRQ still
enabled). When detected, it patches the running code to insert a SWI
instruction so that on interrupt return it will trigger a SWI and produce
a meaningfull backtrace to debug the deadlock. This should allow to debug
freezes in IRQ context.

Rewrite IRQ handling to allow nested IRQs: on each IRQ entry, we save the
parameters on the (IRQ) stack and then switch to SVC mode (with its own
stack) and renable interrupts. Make sure interrupt is properly acknowledged
by using the read side-effect (RSE) mode and handle priority levels as well.

This patch includes some refactoring:
- renaming according to Rockbox guidelines
- GPIO code merging, still with target defines
- some simplification in firmware/SOURCES

This is the basic port to the new target Samsung
YP-R1, which runs on a similar platform as YP-R0.
Port is usable, although there are still
some optimizations that have to be done.

This should catch the case of buffer misuse which results
in corrupted cookie of next allocation. The check is performed
on move_block() so it may be a bit late.
There is buflib_check_valid() provided which checks the
integrity of all cookies for given context.
On DEBUG build with --sdl-thread this check is carried out
for core_ctx on every context switch to catch problems earlier.

The only true difference in this platform is the amount of iram
between MCF5249 and MCF5250. Instead of duplicating the file
simply use one with proper ifdefs.

This fixes the radioart crash that was the result of buffering.c working
on a freed buffer at the same time as buflib (radioart uses buffering.c for the
images). With this change the buffer is owned by buflib exclusively so this
cannot happen.
As a result, audio_get_buffer() doesn't exist anymore. Callers should call
core_alloc_maximum() directly. This buffer needs to be protected as usual
against movement if necessary (previously it was not protected at all which
cased the radioart crash), To get most of it they can adjust the willingness of
the talk engine to give its buffer away (at the expense of disabling voice
interface) with the new talk_buffer_set_policy() function.

Leaving the card in TRAN results in a huge power consumption because some cards
and internal bridges do not automatically enter power saving mode in TRAN state.

The ZEN/ZEN-XFi seem to be very picky about the lcd. And they do not like
standby mode so I'm going to drop it, the OF doesn't use it anyway. I still
don't know what this "power" pin is about, obviously it's not real power but
the OF toggle it. Let's hope the lcd will finally become more stable with
fix: the driver now does full power on/off on enable/disable.
