mainboard/qemu-aarch64: Get top of memory from device-tree blob
Trying to probe RAM space to figure out top of memory causes an exception on AArch64 virtual machines with recent versions of QEMU, but we temporarily enable exception handlers for that and use it to help detect if a RAM address is usable or not. However, QEMU docs recommend reading device information from the device-tree blob it provides us at the start of RAM. A previous commit adds a library function to parse device-tree blob that QEMU provides us. Use it to determine top of memory in AArch64 QEMU virtual machines, but still fall back to the RAM probing approach as a last-ditch effort.
