charset="utf-8" Some sysbus devices have conditional mmio regions. This happens for instance with the hw/acpi/ged device. In that case it becomes difficult to predict which index a specific MMIO region corresponds to when one needs to mmio map the region. Introduce a new helper that takes the name of the region instead of its index. If the region is not found this returns -1. Otherwise it maps the corresponding index and returns this latter.
