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.
