[PULL 29/33] hw/riscv: opentitan: Use MachineState::ram and MachineClass::default_ram_id |

From: Bin Meng <bmeng.cn@gmail.com>
Using memory_region_init_ram(), which can't possibly handle vhost-user,
and can't work as expected with '-numa node,memdev' options.
Use MachineState::ram instead of manually initializing RAM memory
region, as well as by providing MachineClass::default_ram_id to
opt in to memdev scheme.
While at it add check for user supplied RAM size and error out if it
mismatches board expected value.
