[MIPS] Fix sparsemem support.
Move memory_present() in arch/mips/kernel/setup.c. When using sparsemem
extreme, this function does an allocate for bootmem. This would always
fail since init_bootmem hasn't been called yet.
Move memory_present after free_bootmem. This only marks actual memory
ranges as present instead of the entire address space.
