hw: Default -drive to if=ide explicitly where it works
Block backends defined with -drive if=ide are meant to be picked up by machine initialization code: a suitable frontend gets created and wired up automatically. if=ide drives not picked up that way can still be used with -device as if they had if=none, but that's unclean and best avoided. Unused ones produce an "Orphaned drive without device" warning. -drive parameter "if" is optional, and the default depends on the machine type. If a machine type doesn't specify a default, the default is "ide". Many machine types default to if=ide, even though they don't actually have an IDE controller. A future patch will change these defaults to something more sensible. To prepare for it, this patch makes default "ide" explicit for the machines that actually pick up if=ide drives: * alpha: clipper * arm/aarch64: spitz borzoi terrier tosa * i386/x86_64: generic-pc-machine (with concrete subtypes pc-q35-* pc-i440fx-* pc-* isapc xenfv) * mips64el: fulong2e * mips/mipsel/mips64el: malta mips * ppc/ppc64: mac99 g3beige prep * sh4/sh4eb: r2d * sparc64: sun4u sun4v Note that ppc64 machine powernv already sets an "ide" default explicitly. Its IDE controller isn't implemented, yet.
