Apple silicon SoCs have numerous embedded co-processors with pre-loaded firmware. The co-processors text and data sections need to be mapped via DART iommus controlled by the main processor. Those sections are exported as reserved-memory. Bump CONFIG_LMB_MAX_REGIONS from 8 to 64 to deal with the large amount of reserved-memory regions.
