[PULL 060/136] ppc/mac_newworld: use memdev for RAM

[Paolo Bonzini]

From: Igor Mammedov <address@hidden>

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.
