Convert to use folios then remove find_subpage(), thp_nr_pages()

This patch series is premature. None of these APIs are particularly
advantageous to remove (they're inline functions, so cost nothing unless
used).
I do enjoy seeing the removal of thp_nr_pages(), though :)
The thp_nr_pages() and PageTransHuge() removing are found when improve
memory hotplug[1], also find_subpage() has issue[2], this is where
patches come from, since there are only few callers, I think we can
cleanup it earlier?
