Subject: [PATCH -next] RISCV: Add some depends for NUMA

The numa feature is useless for riscv32 platform(MAXPHYSMEM_1GB if 32bit),
and it should depends on SMP feature, this also fix the build error,

  riscv64-buildroot-linux-gnu-ld: mm/page_alloc.o: in function `.L0 ':
  page_alloc.c:(.text+0x4808): undefined reference to `node_reclaim_distance'

Fixes: 4f0e8eef772e ("riscv: Add numa support for riscv64 platform")
