mips/mips_r4k: use memdev for RAM
memory_region_allocate_system_memory() API is going away, so replace it with memdev allocated MemoryRegion. The later is initialized by generic code, so board only needs to opt in to memdev scheme by providing MachineClass::default_ram_id and using MachineState::ram instead of manually initializing RAM memory region.
