[PATCH 12/14] MIPS: memblock: Discard bootmem from Loongson3 code

[Serge Semin]

Loongson64/3 runs its own code to initialize memory allocator in
case of NUMA configuration is selected. So in order to move to the
pure memblock utilization we discard the bootmem allocator usage
and insert the memblock reservation method for kernel/addrspace_offset
memory regions.
