aarch64: deduplicate MMIO region calculations

The get_high_mmio_base_size() function duplicates and hard-codes the
math from get_platform_mmio_base_size(). Since these are both only
called in one location now, pull them into get_resource_allocator() so
the plat_mmio variables can be used instead of duplicating the math.

Also reorder the SystemAllocator::builder() calls so that they are in
the same order as the layout of the regions in memory; this makes no
functional difference, but it is less confusing to read.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
