kvmtool: initial support

Add CONFIG_KVMTOOL config option.

kvmtool supports virtio only, so disable drivers
for all kinds of qemu emulated hardware and leave
only virtio-blk and virtio-scsi enabled.

Set rom default size to 128k.
Enable serial console for kvmtool.
Add ram detection.
Add pci devices scan.
