include/linux/mmzone.h: clean up watermark accessors

Browse Source 
- we have a helper wmark_pages().  Teach min_wmark_pages(),
  low_wmark_pages(), high_wmark_pages() and promo_wmark_pages() to use
  it instead of open-coding its implementation.

- there's no reason to implement all these things as macros.  Redo them
  in C.
