[PATCH 3/3] arch/sh: use __page_aligned_bss

[Jeremy Fitzhardinge]

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:
