Add the two RKNN cores and their IOMMUs, plus the NPU power-domain resets the pmdomain driver now cycles on power-on. Both cores are disabled by default; boards enable what they wire up. Each core lists both NPU power domains, its own first. The compute path needs NPU1 powered even when only core 0 runs, and a node with a single domain would be auto-attached by the driver core before the driver can attach the list itself. The IOMMUs keep one domain each, since they rely on that same auto-attach.
