The sci_probe_single() path attempts to use sci_remove() for the error
path, while sci_remove() is still flagged as __devexit. So, we simply

sh64 has traditionally had this configurable via a Kconfig option
(CONFIG_SH64_USER_MISALIGNED_FIXUP). In practice it has never really been
terribly useful to turn this off, so just get rid of the option entirely.

We leave the sysctl around so we don't end up breaking existing root
file systems, and to allow folks that really want this off to do so at
their own risk.

Now that everything has converted over to generic timekeeping, we need an

maintain the same behaviour.
