To increase performance of audio application code, the SOF heap should
be mapped to cached address region on platforms with aliased
cached/uncached memory layout.
This splits the heap into two and maps the SOF_MEM_ZONE_BUFFER to
the cached heap and all rest to uncached heap.
The raw heap memory area is still mapped to uncached memory, even for
the cached heap. The allocated blocks are converted to cached addresses
and passed to SOF users of rmalloc() and rballoc_align(). To ensure
application buffers do not share cachelines with heap metadata chunks,
allocation sizes are rounded up to integer multiples of platform
cacheline size.

The key-phrase-buffer (kpb) component can be included in
Zephyr-based builds, but the component is not initialized
properly in the builds.

Notifier data has to be per-core and its allocation is
performed in init_system_notify(), no need to also do it in
architecture code.

sof_main() doesn't run on secondary cores. Instead we provide
a new function, that initialises a dummy thread, runs SOF
initialisation by calling secondary_core_init() and switches
over to the dummy thread.

The use of Zephyr LOG_*() API in SOF is breaking compilation.
Replace it with with the native trace logging until a proper
fix is available.

SOF registers IRQ handlers dynamically, therefore disabling
support for dynamic interrupts for SOF builds doesn't make
much sense. However, this can be used to at least increase
compile-time testing coverage and potentially enable
applications, not using dynamic interrupt registration.

The Zephyr timer implementation reads high and low 32 bits
in a non-atomic way. Add a loop to make sure the read is
consistent.

When building SOF with Zephyr for unsupported architectures
the following additional adjustments to the wrapper are required:
1. define HEAP_RUNTIME_SIZE
2. implement stubs for interrupt handlich code
3. remove arch_timer_get_system() as it's provided by a header
4. hardcode "return 0;" for platform_timer_get()
5. disable sys_module_init() which anyway isn't yet functional
under Zephyr
6. add dummy platform_init() and platform_boot_complete()
7. add log_const_sof

Broadwell support with Zephyr had only been dry-coded, it has never
been tested, and it contains an infinite recursion bug: functions
platform_timer_get() and arch_timer_get_system() call each other
infinitely. Break the recursion formally, until a proper fix is
available.

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.

Add a wrapper to convert SOF API calls to Zephyr equivalents. This allows
development to continue in parallel with xtos/HAL and Zephyr RTOSes until
parity is reached.
The initlial Zephyr APIs to be used are HAL, boot, IRQs, scheduling and
memory. The wrapper reflects this and will probably grow until feature
parity is reached when it can be deleted (as Zephyr APIs can be used
directly).
