memblock: extract page freeing from free_reserved_area() into a helper

Browse source

There are two functions that release pages to the buddy allocator late in
the boot: free_reserved_area() and memblock_free_late().

Currently they are using different underlying functionality,
free_reserved_area() runs each page being freed via free_reserved_page()
and memblock_free_late() uses memblock_free_pages() -> __free_pages_core(),
but in the end they both boil down to a loop that frees a range page by
page.

Extract the loop frees pages from free_reserved_area() into a helper and
use that helper in memblock_free_late().
