These are converted in transactions on a side band bus, the DCR bus, which connects the on-SoC devices to the CPU. Ideally, we should model these accesses with a DCR namespace and DCR memory regions but today the DCR handlers are installed in a DCR table under the CPU. Instead, introduce a little device model wrapper to hold a CPU link and handle registration of DCR handlers. The DCR device inherits from SysBus because most of these devices also have MMIO regions and/or IRQs. Being a SysBusDevice makes things easier to install the device model in the overall SoC.
