zephyr: wrapper: complete zephyr support for working audio This patch finalises the wrapper to allow LL scheduling of timer domain audio, EDF sccheduling of IPC, trace re-direction and kconfig build support. There are still many items that are WIP and have been marked with TODO: comments. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>

zephyr/atomic.h: add a no-op cast: (long)atomic_read() Zephyr commit 174cb7f9f183 switched 'atomic_t' from 'int' to 'long' and broke SOF compilation as shown below. Recent SOF commit 970d7d61ece9 ("zephyr: update print messages for 64-bit atomics") switched all atomic_read() logs to "%ld" instead of "%d" which fixed compilation with Zephyr after the switch but broke it with Zephyr _before_ the switch. This no-op (long) cast makes SOF compatible with Zephyr both before and after the switch. Note the sof-logger does not make any difference between %ld and %d and does not care. Sample failure: src/lib/dma.c: In function 'dma_get': sof/src/include/sof/trace/trace.h:290 error: format '%d' expects argument of type 'int', but argument 5 has type 'atomic_val_t' {aka 'long int'} [-Werror=format=] 290 | printk("%llu " format "\n", platform_timer_get(NULL), \ | ^~~~~~~ sof/src/lib/dma.c:119:2: note: in expansion of macro 'tr_info' 119 | tr_info(&dma_tr, "..., busy channels = %d", atomic_read(...))

/* Zephyr commit 174cb7f9f183 switched 'atomic_t' from 'int' to
* 'long'. As we don't support 64 bits, this should have made no
* difference but in reality it broke printk("%d / %ld",...) The no-op
* cast to 'long' below provides a transition by making it possible to
* compile SOF both before _and_ after the Zephyr switch.
