arch/tile: catch up with section naming convention in 2.6.35

The convention changed to, e.g., ".data..page_aligned". This commit
fixes the places in the tile architecture that were still using the
old convention. One tile-specific section (.init.page) was dropped
in favor of just using an "aligned" attribute.

Sam Ravnborg <[e-mail]> pointed out __PAGE_ALIGNED_BSS, etc.
