[PATCH] hw/riscv/virt.c: Make block devices default to virtio

[Sunil V L]

RISC-V virt is currently missing default type for block devices. Without
this being set, proper backend is not created when option like -cdrom
is used. So, make the virt board's default block device type be
IF_VIRTIO similar to other architectures.

We also need to set no_cdrom to avoid getting a default cdrom device.
