mips: Use memblock to reserve the __nosave memory range
Originally before legacy bootmem was removed, the memory for the range was correctly reserved by reserve_bootmem_region(). But since memblock has been selected for early memory allocation the function can be utilized only after paging is fully initialized (as it is done by memblock_free_all() function). So calling it from arch_mem_init() method is prone to errors, and at this stage we need to reserve the memory in the memblock allocator.
