Andrey Borisovich 2e04bfdfe0 soc: intel_adsp: Refactored IPC/IDC
Changes to code:
1. Renamed CAVS_IPC API from common/include/cavs_ipc.h to
common/include/intel_adsp_ipc.h. Renamed all API functions and structs -
added "intel_adsp_" prefix.
2. Moved definitions from intel-ipc-regs.h and ace-ipc-regs.g to SOC
specific headers include/<soc_name>/adsp_ipc_regs.h.
3. Added new common intel_adsp_ipc_devtree.h header with new
macros to retrieve IPC and IDC nodes and register addresses.
Put those new macros in code replacing hardcoded values outside of
devicetree.
4. Changed documentation of IDC and renamed IDC register struct
to have common name between all intel adsp socs.
5. Removed excessive docs description on cAVS IPC protocol.

Changes to Devicetree:
1. Renamed in all CAVS boards .dtsi files content in IPC nodes:
   - "cavs_host_ipc" node labels to "adsp_ipc" labels.
   - compatible "intel,cavs-host-ipc" renamed to
     "intel,adsp-host-ipc".
2. Added (previously missing) yaml file for "intel,adsp-host-ipc"
   compatible.
3. Renamed in all CAVS boards .dtsi files content in IDC nodes:
   - "idc" node labels to "adsp_idc" labels.
   - compatible "intel,cavs-idc" renamed to "intel-adsp-idc"
4. Renamed intel,cavs_idc.yaml file to intel,adsp_idc.yaml
   so it is suitable for both CAVS and ACE SoC family.
   Moved it from ipm bindings to ipc bindings where it belongs.

Changes to Kconfig:
1. Renamed existing Kconfig option CONFIG_CAVS_IPC to
   INTEL_ADSP_IPC.
2. For renamed INTEL_ADSP_IPC addded default value based on
   status of the "adsp-ipc" and "adsp-ipc" node.

Anas Nashif 2d87948818 drivers: ipm/spi/intc: remove Intel S1000 support
Remove intel_s1000_crb support. The board is no longer available or
supported in the zephyr tree.

Andy Ross a7af0acfc2 soc/intel_adsp: Clean up IPM compiler guards
The CAVS_IDC_IPM driver happens to be used only on non-2.5 hardware,
but it's best to be clear in the conditional compilation when we're
talking about hardware-dependencies and when we mean software
configuration.  This was mixed up in a few spots.

Also fix a warning that creeps in on non-default drivers choices about
an undeclared ipm function.

Andy Ross ed9434c812 soc: intel_adsp: Clean up shim driver
Each platform was defining its own shim.h header, with slightly
variant field definitions, for a register block that is almost
completely compatible between versions.  This is made worse by the
fact that these represent an API imported fairly early from SOF, the
upstream version of which has since diverged.

Move the existing shim struct into a header ("cavs-shim.h") of its
own, remove a bunch of unused symbols, fill in definitions for some
registers that were left out, correct naming to match the hardware
docs in a few places, make sure all hardware dependencies are source
from devicetree only, and modify existing usage to use the new API
exclusively.

Interestingly this leaves the older shim.h header in place, as it
turns out to contain definitions for a bunch of things that were never
part of the shim register block.  Those will be unified in separate
patches.

Finally: note that the existing IPM_CAVS_IDC driver (soon to be
removed from all the intel_adsp soc's) is still using the old API, so
redeclare the minimal subset that it needs for the benefit of the
platforms in transition.

Anas Nashif dc9127e93a ipm: cavs_idc: use the IPC/IDC definitions in SoC
The SoC definitions have the necessary IPC/IDC bits so there is
no need to define them separately.

Daniel Leung 492e890cd6 ipm: add driver for the CAVS DSP Intra-DSP Communication (IDC)
This adds a rather primitive driver for use with the Intra-DSP
Communication (IDC) on the DSP on certain Intel SoCs. The IDC
generates interrupts from one core to another by writing to
certain registers. This is also being utilized as
the scheduler IPI since it can interrupt other cores.
