MIPS: Loongson: Switch from flatmem to sparsemem

With flatmem hibernation for Loongson will fail, and there are also some
other problems such as broken files when using NFS or CIFS / Samba.

The config help of sparsemem says:

"This option provides some potential performance benefits, along with
decreased code complexity."

So to avoid the potential problems of FLATMEM, we disable FLATMEM directly
and use SPARSEMEM instead.
