mips: Select SPARSEMEM_EXTREME
Commit c46173183657 ("MIPS: Add NUMA support for Loongson-3") has increased
.bss size of the Octeon kernel from 16k to 16M. Providing the conditions
for SPARSEMEM_EXTREME avoids the waste of memory.
Thomas has tested the loogsoon64 kernel, where .bss is being reduced by
this patch from 16.5M to 515k.
