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:
- while at it add check for user supplied RAM size and error
out if it mismatches board expected value.
- introduce RAM_ADDR_UFMT to avoid build errors on 32-bit hosts
when specifying format string for ram_addr_t type

v2:
* fix format string causing build failure on 32-bit host
(Philippe Mathieu-Daudé <phi...@redhat.com>)
v3:
* instead of RAM_ADDR_UFMT adding use size_to_str()
