sparc32: Limit memblock allocation to low memory
[ Upstream commit bda1669 ] Commit cca079e changed sparc32 to use memblocks instead of bootmem, but also made high memory available via memblock allocation which does not work together with e.g. phys_to_virt and can lead to kernel panic. This changes back to only low memory being allocatable in the early stages, now using memblock allocation.
