[PATCH] hugepage: Move hugetlb_free_pgd_range() prototype to hugetlb.h

The optional hugepage callback, hugetlb_free_pgd_range() is presently
implemented non-trivially only on ia64 (but I plan to add one for powerpc
shortly).  It has its own prototype for the function in asm-ia64/pgtable.h.
 However, since the function is called from generic code, it make sense for
its prototype to be in the generic hugetlb.h header file, as the protypes
other arch callbacks already are (prepare_hugepage_range(),
set_huge_pte_at(), etc.).  This patch makes it so.
