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.
