The current ARM64 lowlevel code needs the exception vector to set
up all the ELs. Select ARM_EXCEPTIONS to make sure this is always
present.

We don't yet have an implementation for those two features on ARM64, so move
them to a place where they are only selected for a 32bit barebox.

ARM64 has native instructions for division and thus doesn't need the
helper functions implemented in those files.
