This implements basic driver to utilize the I3C IP block on NPCX. 1. I3C mode: Main controller mode only. 2. Transfer: Support SDR only. 3. IBI: Support Hot-Join, IBI(MDB). Controller request is not supported. 4. Support 3 I3C modules: I3C1(3.3V), I3C2(1.8V, espi mode), (I3C3 1.8V or 3.3V) Signed-off-by: Alvis Sun <yfsun@nuvoton.com>
