milkymist-minimac2: Just expose buffers as a sysbus mmio region 

Just expose the register buffers memory as a standard sysbus mmio
region which the creator of the device can map, rather than
providing a qdev property which the creator has to set to the
base address and then doing the mapping in the device's own
init function.
