cbmem: use aligned_memcpy for reading cbmem address information
The coreboot table entry containing the memory entries can have fields unnaturally aligned in memory. Therefore one needs to perform an aligned_memcpy() so that it doesn't cause faults on certain architectures that assume naturally aligned accesses.
