Change all lcd drivers to using a pointer to the static framebuffer
instead of directly accessing the static array. This will let us
later do fun things like dynamic framebuffer sizes (RaaA) or
ability to use different buffers for different layers (dynamic
skin backdrops!)

Fixes swapped left and right channels on ipod 6g and changes the
i2s config to send samples as 16 bits instead of 16 zero padded to
24 bits to the dac.

GPIOA pin 1 used for USB DAC. This configures IO mux for using
GPIOA 0-4 pins instead of lcd data16-18,20,22, which are not needed,
because hifiman's lcd works in 16bit mode.

Simplified stack unwinder for ARM. This is port of
http://www.mcternan.me.uk/ArmStackUnwinding/
backtrace() is called from UIE() on native targets
and from panicf() on both native and ARM RaaA.

- PCM playback DMA doesn't need the discard. Only recording DMA would
need it.
- When creating threads for another core, the core creating the thread only
needs to commit. The discard on the other core is handled elsewhere.

The headphone volume register value reads differently in Line1 and DAC mode.
Since the volume is not set again when switching between playback and radio,
we need to remember the hp volume and reapply setting when changing the mode.

We neet to setup the XPD to work as GPIO

Now lcd_framebuffer is the only framebuffer in the system. We still use a ARM-buffered buffer
which serve as an intermediate buffer for copying, to accomodate the requirement of the controller.
We implement lcd_update_rect() properly using this new scheme (this requires two little quirks),
this allows to implement lcd_blit_yuv with the right semantic (bypasses the framebuffer). YUV to RGB
conversion is still done in software but the DCP CSC should be able to do that but the hardware rotation
scheme is not the same as our software so it will require some tricks.

This dir is suitable for stuff that doesn't fit the target tree, e.g. because
it also builds on hosted or otherwise. It also has a generic subfolder for
fallback C implementations so that not all archs need to provide asm files.
SOURCES should only contain "foo.c" where foo.c includes the specific
<arch>/foo.c files from the subdirs using the preprocessor. This way automatic
selection of asm versions or generic C verion is possible.
For the start, the thread support files are moved, since ASM threads can
be used on hosted platforms as well. Since core_sleep() remains platform
specific it's moved to the corresponding system.h headers.

Core, codecs and plugins link it separately so this gets rid of SOURCES trickery.
Don't build it for hosted targets.

Mostly for the sake of reducing latency for audio servicing where other service
routines can take a long time to complete, leading to occasional drops of a
few samples, especially in recording, where they are fairly frequent.
One mystery that remains is GPIOA IRQ being interrupted causes strange
undefined instruction exceptions, most easily produced on my Fuze V2 with a
scrollwheel. Making GPIOA the top ISR for now, thus not interruptible, cures it.
SVC mode is used during the actual calls. Hopefully the SVC stack size is
sufficient. Prologue and epilogue code only uses the IRQ stack and is large
enough.
Any routine code that should not be interrupted should disable IRQ itself from
here on in.
