arm64: lib: Consistently enable crc32 extension

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Currently most of the assembly files that use architecture extensions
enable them using the .arch directive but crc32.S uses .cpu instead. Move
that over to .arch for consistency.
