mips: Select SPARSEMEM_EXTREME

Commit c461731 ("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.
