mm: move free_reserved_area() to mm/memblock.c
free_reserved_area() is related to memblock as it frees reserved memory
back to the buddy allocator, similar to what memblock_free_late() does.
Move free_reserved_area() to mm/memblock.c to prepare for further
consolidation of the functions that free reserved memory.
No functional changes.
