If default main_mem is used to be registered as the system memory,
other memory cannot be initialized. Therefore, the system memory
should be initialized to the machine->ram, which consists of the
default main_mem and other possible memory required by applications,
such as shared hugepage memory in DPDK.
Also, the mc->defaul_ram_id should be set to the default main_mem,
such as "riscv_virt_board.ram" for the virt machine.
