According to the 82371FB documentation (82371FB.pdf, 2.3.9. BMIBA-BUS
MASTER INTERFACE BASE ADDRESS REGISTER, April 1997), the register is
32bit wide. To properly reset it to default values, all 32bit need to be
cleared. Bit #0 "Resource Type Indicator (RTE)" needs to be enabled.
The initial change wrote just the lower 8 bit, leaving parts of the "Bus
Master Interface Base Address" address at bit 15:4 unchanged.

The modern, declarative way to set up VM state handling is to assign to
DeviceClass::vmsd attribute.
There shouldn't be any change in behavior since dc->vmsd causes
vmstate_register_with_alias_id() to be called on the instance during
the instance init phase. vmstate_register() was also called during the
instance init phase which forwards to vmstate_register_with_alias_id()
internally. Checking the migration schema before and after this patch confirms:
before:

This function was declared in a generic and public header, implemented
in a device-specific source file but only used in xen_platform. Given its
'aux' parameter, this function is more xen-specific than piix-specific.
Also, the hardcoded magic constants seem to be generic and related to
PCIIDEState and IDEBus rather than piix.
Therefore, move this function to xen_platform, unexport it, and drop the
"piix3" in the function name as well.

-drive file=/root/disk_file,if=ide,index=0,media=disk,format=raw
Since the code already have the IDE controller as `dev`, we don't need
to use the legacy DriveInfo to find all the drive we want to unplug.

request unplug of 'aux' disks (which is stated to mean all IDE disks,

NOTE: The semantics of what happens if unplug of all disks and 'aux' disks
is simultaneously requests is not clear. The patch makes that
assumption that an 'all' request overrides an 'aux' request.

of trying to flush ALL devices. This removes the last user of

Device models should access their block backends only through the
block-backend.h API. Convert them, and drop direct includes of
inappropriate headers.
Just four uses of BlockDriverState are left:
* The Xen paravirtual block device backend (xen_disk.c) opens images
itself when set up via xenbus, bypassing blockdev.c. I figure it
should go through qmp_blockdev_add() instead.
* Device model "usb-storage" prompts for keys. No other device model
does, and this one probably shouldn't do it, either.
* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
which has only the BlockDriverState.
* PC87312State has an unused BlockDriverState[] member.
The next two commits take care of the latter two.

The patch is big, but all it really does is replacing
dinfo->bdrv
by
blk_bs(blk_by_legacy_dinfo(dinfo))
The replacement is repetitive, but the conversion of device models to
BlockBackend is imminent, and will shorten it to just
blk_legacy_dinfo(dinfo).
Line wrapping muddies the waters a bit. I also omit tests whether
dinfo->bdrv is null, because it never is.

drive_del() has become a trivial wrapper around blk_unref(). Get rid
of it.

The function is empty after the previous patch, so remove it.

It's always one since commit fa510eb dropped the last drive_get_ref().
