The early boot gigantic hugepage allocation helpers currently mix allocation with huge_bootmem_page setup, and leave part of the initialization flow in architecture code. Refactor the interface to return the allocated huge page pointer and move the huge_bootmem_page setup into the generic hugetlb code. This makes the architecture-specific paths focus only on finding memory, while the common code handles node placement and early page metadata setup in one place. This also lets powerpc benefit from memblock_reserved_mark_noinit(), which it did not enable before. In addition, upcoming cross-zone validation for boot-time gigantic hugetlb reservation is common logic. With this refactoring, that logic can stay in the generic code instead of being duplicated in architecture-specific paths.
