memblock: Add arch function to control coalescing of memblock memory regions
Some archs such as ARM want to avoid coalescing accross things such as the lowmem/highmem boundary or similar. This provides the option to control it via an arch callback for which a weak default is provided which always allows coalescing. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
