Subject: [PATCH] kvm2 driver: Use scsi cdrom for arm64

On linux/aarch64 (e.g. Asahi Linux on MacBook M*) booting from SATA
cdrom is broken and the VM drops into the UEFI shell.

It seems that linux/aarch64 supports only virtio and scsi devices[1].
Replace with scsi cdrom (like the x86 version) and addd a virtio-scsi
controller since the default scsi controller does not boot as well.

Fixes #18238
