hw/i386: Deprecate -drive if=scsi with PC machine types
The PC machines (pc-q35-* pc-i440fx-* pc-* isapc xenfv) automatically create lsi53c895a SCSI HBAs and SCSI devices to honor -drive if=scsi. For giggles, try -drive if=scsi,bus=25,media=cdrom --- this makes QEMU create 25 of them. lsi53c895a is thoroughly obsolete (PCI Ultra2 SCSI, ca. 2000), and currently has no maintainer in QEMU. megasas is a better choice, except with old OSes that lack drivers. virtio-scsi is a much better choice when you have a driver, but only (newish) Linux comes with one in the box. There is no good default that works for all guests. Encourage users to pick a non-obsolete SCSI HBA that works for them by deprecating -drive if=scsi.
