mircoblaze: drop unneeded NUMA and sparsemem initializations 

microblaze does not support neither NUMA not SPARSMEM, so there is no
point to call memblock_set_node() and
sparse_memory_present_with_active_regions() functions during microblaze
memory initialization.

Remove these calls and the surrounding code.
