arm/digic_boards: 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.

PS:
 remove no longer needed DigicBoardState

PS2:
 while at it add check for user supplied RAM size and error
 out if it mismatches board expected value.
