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.
