DMAs on TI K3 SoCs have channel configuration registers region which are usually hidden from Linux and configured via Device Manager Firmware APIs. But certain early SWs like bootloader which run before Device Manager is fully up would need to directly configure these registers and thus require to be in DT description. This add bindings for such configuration regions. Backward compatibility is maintained to existing DT by only mandating existing regions to be present and this new region as optional.
