sh: Use the now generic SH-4 clear/copy page ops for all MMU platforms.
Now that the SH-4 page clear/copy ops are generic, they can be used for all platforms with CONFIG_MMU=y. SH-5 remains the odd one out, but it too will gradually be converted over to using this interface. SH-3 platforms which do not contain aliases will see no impact from this change, while aliasing SH-3 platforms will get the same interface as SH-4. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
