[PATCH 02/22] mm: move mm_flags helpers to mm_types.h

[Kevin Brodsky]

Some of the mm_flags helpers are defined in <linux/mm_types.h>,
while others are defined in <linux/mm.h>. We will soon need to call
one of the latter helpers from mm_types.h.

Regroup all the helpers in mm_types.h to keep things simple.

Also remove #include's that were added specifically for these
helpers in mm.h.
