sysbus: Expose MMIO enumeration helper

Browse source 
Sysbus devices have a range of MMIO regions they expose. The exact number
of regions is device specific and internal information to the device model.

Expose whether a region exists via a public interface. That way our platform
bus enumeration code can dynamically determine how many regions exist.
