For now, this just protects against programming errors like having the
same drive back multiple non-qdev devices, or untimely bdrv_delete().
Later commits will add other interesting uses.
While there, rename BlockDriverState member peer to dev, bdrv_attach()
to bdrv_attach_dev(), bdrv_detach() to bdrv_detach_dev(), and
bdrv_get_attached() to bdrv_get_attached_dev().

The SDIO specification introduces new commands 52 and 53.
Handle as illegal command but do not complain on stderr,
as SDIO-aware OSes (including Linux) may legitimately use
these in their probing for presence of an SDIO card.

sd_set_cb() calls bdrv_is_read_only() and bdrv_is_inserted() even if
no block driver is associated with the card reader.
This patch fixes the issues by not setting the irq in this case, this
fixes ARM versatile crash.

The SD_STATUS and SEND_NUM_WR_BLOCKS commands are supposed to cause
the card to send data back to the host. However sd.c was missing the
state change to sd_sendingdata_state for these commands, with the effect
that the Linux driver would either hang indefinitely waiting for
nonexistent data (pl181) or read zeroes and provoke a qemu warning
message (omap).

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

Eliminate "mmc0: SD card claims to support the incompletely defined 'low voltage
