arch/sh: use __page_aligned_bss

The patch "make page-aligned data and bss less fragile" introduces __page_aligned_data and __page_aligned_bss to make sure that page aligned things remain so, even if there are non-page-sized page-aligned things.

This paragraph converts the two C instances of page-aligned bss variables to use them. It's a purely decorative patch.

If the first patch hits mainline then I'll take this directly in to my tree, otherwise:
