AM62A SoC has a dedicated BCDMA that serves Camera Serial Interface
(CSI) IP. Add new compatible for the same. Unlike system
BCDMA, this instance only has RX DMA channels and lack TX or block copy
channel. Thus make those properties optional. Additionally CSI RX has
independent power domain, add the binding for the same.
