Mikael Olsson	b139f1cf97	feat(ethos-n)!: add support for SMMU streams The Arm(R) Ethos(TM)-N NPU driver now supports configuring the SMMU streams that the NPU shall use and will therefore no longer delegate access to these registers to the non-secure world. In order for the driver to support this, the device tree parsing has been updated to support parsing the allocators used by the NPU and what SMMU stream that is associated with each allocator. To keep track of what NPU device each allocator is associated with, the resulting config from the device tree parsing will now group the NPU cores and allocators into their respective NPU device. The SMC API has been changed to allow the caller to specify what allocator the NPU shall be configured to use and the API version has been bumped to indicate this change.

feat(ethos-n)!: add support for SMMU streams

The Arm(R) Ethos(TM)-N NPU driver now supports configuring the SMMU
streams that the NPU shall use and will therefore no longer delegate
access to these registers to the non-secure world. In order for the
driver to support this, the device tree parsing has been updated to
support parsing the allocators used by the NPU and what SMMU stream that
is associated with each allocator.

To keep track of what NPU device each allocator is associated with, the
resulting config from the device tree parsing will now group the NPU
cores and allocators into their respective NPU device.

The SMC API has been changed to allow the caller to specify what
allocator the NPU shall be configured to use and the API version has
been bumped to indicate this change.

feat(drivers/arm/ethosn)!: multi-device support

Add support for Arm Ethos-N NPU multi-device.

The device tree parsing currently only supports one NPU device with
multiple cores. To be able to support multi-device NPU configurations
this patch adds support for having multiple NPU devices in the device
tree.

To be able to support multiple NPU devices in the SMC API, it has been
changed in an incompatible way so the API version has been bumped.

Add SiP service to configure Arm Ethos-N NPU

By default the Arm Ethos-N NPU will boot up in secure mode. In this mode
the non-secure world cannot access the registers needed to use the NPU.
To still allow the non-secure world to use the NPU, a SiP service has
been added that can delegate non-secure access to the registers needed
to use it.

Only the HW_CONFIG for the Arm Juno platform has been updated to include
the device tree for the NPU and the platform currently only loads the
HW_CONFIG in AArch64 builds.
