feat(ethos-n): add separate RO and RW NSAIDs
To be able to further restrict the memory access for the Arm(R)
Ethos(TM)-N NPU, separate read-only and read/write NSAIDs for the
non-protected and protected memory have been added to the Juno
platform's TZMP1 TZC configuration for the NPU.
The platform definition has been updated accordingly and the NPU driver
will now only give read/write access to the streams that require it.
