blockdev: Deprecate -drive with bogus interface type
Drives with interface types other than if=none are for onboard
devices. Unfortunately, any such drives the board doesn't pick up can
still be used with -device, like this:
$ qemu-system-x86_64 -nodefaults -display none -S -drive if=floppy,id=bogus,unit=7 -device ide-cd,drive=bogus -monitor stdio
QEMU 5.0.50 monitor - type 'help' for more information
(qemu) info block
bogus: [not inserted]
Attached to: /machine/peripheral-anon/device[0]
Removable device: not locked, tray closed
(qemu) info qtree
bus: main-system-bus
type System
[...]
bus: ide.1
type IDE
dev: ide-cd, id ""
---> drive = "bogus"
[...]
unit = 0 (0x0)
[...]
This kind of abuse has always worked. Deprecate it:
qemu-system-x86_64: -drive if=floppy,id=bogus,unit=7: warning: bogus if=floppy is deprecated, use if=none
