cbmem: Add custom aligned memcpy() implementation

On some architectures (like AArch64), /dev/mem mappings outside of the
area marked as normal RAM use a memory type that does not support
unaligned accesses. The libc memcpy() implementation on these
architectures may not know or expect that and make an unaligned access
for certain source/dest/length alignments. Add a custom memcpy()
implementation that takes these restrictions into account and use it
anywhere we copy straight out of /dev/mem memory.
