mm, treewide: introduce NR_PAGE_ORDERS
[ Upstream commit fd37721803c6e73619108f76ad2e12a9aa5fafaf ]
NR_PAGE_ORDERS defines the number of page orders supported by the page
allocator, ranging from 0 to MAX_ORDER, MAX_ORDER + 1 in total.
NR_PAGE_ORDERS assists in defining arrays of page orders and allows for
more natural iteration over them.
