ARM64 support does not allow mach-* directories at all. While we may not get to that given all the non-standard architectures we support, we should still try to get as close as we can and reduce the number of mach directories. The mach-sunplus/ directory and files, provides just one "feature": having the kernel print the machine name if the DTB does not also contain a "model" string (which they always do). To reduce the number of mach-* directories let's do without that feature and remove this directory. NOTE: The default l2c_aux_mask is now ~0 but these devices never have this type of cache controller so this is safe.
