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.
