This is in preparation for adding support for ARM64 platforms where it doesn't use port mapped IO for ACPI IO space. We are making changes so that MMIO region can be accommodated and board can pass the base address into the aml build function. Also move few MEMORY_* definitions to header so that other memory hotplug event signalling mechanisms (eg. Generic Event Device on HW-reduced acpi platforms) can use the same from their respective event handler code.
