feat(ethos-n): add NPU sleeping SMC call
The non-secure world delegation of the register needed to determine if
the Arm(R) Ethos(TM)-N NPU is active or sleeping will be removed in the
future. In preparation for the change, a new SMC call has been added to
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.
