Marcin Maka 3100546463 uuid: add simple static uuids linked to ldc section
Unique identification in form of Guid is much more
scalable for fw parts (components, dais, ...) then
existing ids and trace class ids.

Tomasz Lauda a3e01c805a test: don't use shared section and uncache for unit tests
SHARED_DATA macros doesn't put shared data into separate section
when unit tests are built and uncached memory region is not used.

Tomasz Lauda 80972f1d78 cavs: add section for shared data
This patch adds dedicated section for shared data
on cAVS platforms. This section will be used to store
static data, which can be accessed by multiple cores.
Access to this data will go through uncached memory region.

Adrian Bonislawski f1fe78367a memory: new memory layout for APL, ICL, CNL and SUE
This will optimize memory usage and introduces two significant optimizations:

> Separate the memory (heaps, stack) by cores so if we will turn off a specific core we can also turn off all memory of this core.
> Remove fixed defines and gaps, previously stack was at fixed position: end of memory and buffer heap was everything between stack and fw. Now everything will be packed at sof_fw memory segment and takes only this memory which is really needed, everything else we can turn off.

Changelog:
BSS section now includes heaps and stack
Removed many heap fixed position defines
Removed gap before fw text section
memmap init is using real linker positions for heaps
Temporary stack for boot_ldr placed in heap_hp_buffer (safe)
sof fw max_size and segment limited to memory configured by memory banks count

Using new macro to stack init per core
Stack is no longer a one big block for all cores (core_count*stack_size)
System_runtime_heap and system_heap are no longer a one big block for all cores

For suecreek memory it will also introduce similar changes previously introduced
in other platforms
(One shared memory block SOF_FW for SOF_TEXT, SOF_DATA and SOF_BSS sections
Moved fw_ready near to .rodata and .data)

Memory layout for every slave core aligned to hw memory bank:
--align to memory bank--
system_heap
system_runtime_heap
stack
--align to memory bank--
next slave core..

Similar layout applies to master core

Adrian Bonislawski c06a65a8d0 Memory: self registering ability for audio components
No more need to update global component.h and audio.c component init list

New macro DECLARE_COMPONENT
The component can "register itself" in the appropriate linker section

Example of usage:
DECLARE_COMPONENT(sys_comp_*_init);
