sdhci: Make device "sdhci-pci" unavailable with -device
Device models aren't supposed to go on fishing expeditions for
backends. They should expose suitable properties for the user to set.
For onboard devices, board code sets them.
"sdhci-pci" picks up its block backend in its realize() method with
drive_get_next() instead. Already marked FIXME. See the commit that
added the FIXME for a more detailed explanation of what's wrong.
We can't fix this in time for the release, but since the device is new
in 2.3, we can set cannot_instantiate_with_device_add_yet to disable
it before this mistake becomes ABI, and we have to support command
lines like
$ qemu -drive if=sd -drive if=sd,file=sd.img -device sdhci-pci -device sdhci-pci
forever.
