This driver will subsume the old button-lradc driver and support far more
options. It can sense LRADC channels, PSWITCH, GPIOs and it handles special
"buttons" like headphone insertion and hold detection. It also provides a
more natural description of the buttons using a target-defined table with some
macros to make it easy to read and write. It uniformely handles debouncing on
LRADC channels and PSWITCH.

On some OSes like Windows or if running in a virtual machine, the one second
timeout might be too short.

Original fix by Marcin: it had a problem because crt0 on imx233 is more
complicated than many targets: since we use virtual memory, we first disable
the MMU, then move the entire image (including init and itext stuff), then
setup a temporary stack to setup the MMU. Only when the MMU is enabled, can
we move the init and itext stuff to its right location and finally boot.
This requires some trickery because:
- the initial move copies everything, including init and itext
- the stack overlaps with init and itext to reclaim space
- the temporary stack cannot be the same as the main stack to avoid trashing
the init and itext code, also it needs to be a physical address

Rework the irq code, to put more code in the C part. When interrupt
nesting is enable, Rockbox gets pretty unstable so disable it for now.

Plugins/Applications/main_menu_config allows you to edit the
main menu order without having to manually edit config.cfg.
Press the standard OK button to access the internal menu
which allows you to move items up/down in the order and toggle
their visibility. Exit via this menu to have the order saved.
(Suggestions welcome to improve this UI)

The UI now has a "read-only" check box to prevent accidently changes: once
unchecked, the UI can do write to register (only full register writes are
supported for now). If the register supports it, the UI provides SCT writes
as well. The display register panel was moved to its own class to cleanup
things a bit.

Unfortunately the hardware is not very helpful when changing voltage: in DCDC
mode we have the DC_OK_IRQ but in linear regulator mode, the only available
bit doesn't work when lowering the voltages. At the moment, simply sleep for a
little while before a better solution is found.

On the ZEN, the LCD is fed continuously by the DMA and this refresh needs to
be stop when the bootloader gives control to the firmware, otherwise the DMA
will source data from invalid region and it might even lock-up if the new
code touches the memory setup. Work around this by properly stopping the LCD
driver: the bootloader assumes that if the target defines HAVE_LCD_ENABLE
in bootloader build (which is unusual) then it needs to stop the LCD. Since
stopping the LCD could produce funny screens, power down backlight
which is expected to power down the LCD too, giving a nice black screen
instead of some random pixels.

The old could trigger an immediate IRQ if for example the count was 0
when setting up the timer: since the count was updared *after* clearing the
IRQ, it could fire in between.

The code was a mess with respect to soc handling: some code just plain copied
the SoC descriptor which are big objects, some was using indexes. The new soc
factor out everything in a few classes which hide these ugly details so that
descriptors are never copied.

A SoC descriptor is not a small object: it can be as large as ~100KiB so
it's better to avoid copying things over.

zenxfi2: add support for internal storage on the SD version
The code can now skip devices marked as PROBE if they fail to init, thus
making it possible to handle various kinds of internal storages. The current
code probably doesn't interplay nicely since it acquires pins and never
release them so it will probably break NAND code when it's ready but NAND code
is not ready yet anyway.
