SiP service version number has been bumped up to 15 to reflect these
changes.

feat(ethos-n)!: add protected NPU firmware setup

When the Arm(R) Ethos(TM)-N NPU driver is built with TZMP1 support, the
NPU should use the firmware that has been loaded into the protected
memory by BL2. The Linux Kernel NPU driver in the non-secure world is
not allowed to configure the NPU to do this in a TZMP1 build so the SiP
service will now configure the NPU to boot with the firmware in the
protected memory.

BREAKING CHANGE: The Linux Kernel NPU driver can no longer directly
configure and boot the NPU in a TZMP1 build. The API version has
therefore been given a major version bump with this change.

The SiP service for the Arm(R) Ethos(TM)-N NPU driver will now handle
setting up the address extension and attribute control for the NPU's

extension for stream0 but non-secure access to all other streams have
been removed.

the added functionality.

feat(ethos-n): add SMC call to get FW properties

When the Arm(R) Ethos(TM)-N NPU firmware is loaded by BL2 into protected
memory, the Linux kernel NPU driver cannot access the firmware. To still
allow the kernel driver to access some information about the firmware,
SMC calls have been added so it can check compatibility and get the
necessary information to map the firmware into the SMMU for the NPU.

The API version has been given a minor version bump with this change to
indicate the added functionality.

feat(ethos-n): add check for NPU in SiP setup

The SiP service in the Arm(R) Ethos(TM)-N NPU driver requires that there
is at least one NPU available. If there is no NPU available, the driver
is either used incorrectly or the HW config is incorrect.

To ensure that the SiP service is not incorrectly used, a setup handler
has been added to the service that will validate that there is at least
one NPU available.

to make sure that an event always wakes up the NPU.

The non-secure world delegation of the register needed to determine if

allow the non-secure world to ask the SiP service for the state instead.

A minor API version bump has been done with this change to indicate
support for the new functionality.

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.

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

The device tree parsing currently only supports one NPU device with

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.

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.
