hw/riscv: shakti_c: Use MachineState::ram and MachineClass::default_ram_id
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.
