Commit cca079ef8ac29a7c02192d2bad2ffe4c0c5ffdd0 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.

Each populated sparc_phys_bank is added to memblock.memory. The
reserve_bootmem() calls are replaced with memblock_reserve(), and the
bootmem bitmap initialization is droppped.
