swsusp: free more memory
Move the definition of PAGES_FOR_IO to kernel/power/power.h and introduce SPARE_PAGES representing the number of pages that should be freed by the swsusp's memory shrinker in addition to PAGES_FOR_IO so that device drivers can allocate some memory (up to 1 MB total) in their .suspend() routines without causing the suspend to fail.
