Commit f3d54fc4 factored it out of hw/ide.c for reuse. Sensible,
except it was put into block.c. Device-specific functionality should
be kept in device code, not the block layer. Move it to
hw/hd-geometry.c, and make stylistic changes required to keep
checkpatch.pl happy.

Commit 5bbdbb46 moved it to block.c because "other geometry guessing
functions already reside in block.c". Device-specific functionality
should be kept in device code, not the block layer. Move it back.
Disk geometry guessing is still in block.c. To be moved out in a
later patch series.
Bonus: the floppy type used in pc_cmos_init() now obviously matches
the one in the FDrive. Before, we relied on
bdrv_get_floppy_geometry_hint() picking the same type both in
fd_revalidate() and in pc_cmos_init().

bdrv_get_floppy_geometry_hint() fails to store through its parameter
drive when bs has a geometry hint. Makes fd_revalidate() assign
random crap to drv->drive.
Has been broken that way for ages. Harmless, because:
* The only way to set a geometry hint is -drive if=none,cyls=...
Since commit c219331e, probably unintentional.
* The only use of drv->drive is as argument to another
bdrv_get_floppy_geometry_hint(). Which doesn't use it, since the
geometry hint is still there.
Drop the broken code, ignore -drive parameter cyls, heads and secs for
floppies even with if=none, just like before commit c219331e. Matches
-help, which explains cyls, heads, secs as "hard disk physical
geometry".

Commit 0f588df8b3688b00e77aabaa32e26ece5f19bd39, added code
to ehci_wakeup to kick the async schedule on wakeup, but the else
was positioned wrong making it trigger for devices which are routed
to the companion rather then to the ehci controller itself.
This patch fixes this. Note that the "programming style" with using the
return at the end of the companion block matches how the companion case
is handled in the other ports ops, and is done this way for consistency.

Commit 4be23939ab0d7019c7e59a37485b416fbbf0f073 makes ehci instantly
zap any unlinked queue heads when the guest rings the doorbell.
While hacking up uas support this turned out to be a problem. The linux
kernel can unlink and instantly relink the very same queue head, thereby
killing any async packets in flight. That alone isn't an issue yet, the
packet will canceled and resubmitted and everything is fine. We'll run
into trouble though in case the async packet is completed already, so we
can't cancel it any more. The transaction is simply lost then.

So instead of instantly zapping the queue we'll set a flag that the
queue needs revalidation in case we'll see it again in the schedule.
ehci then checks that the queue head fields addressing / describing the
endpoint and the qtd pointer match the cached content before reusing it.

Make the state fields rx_desc_addr and tx_desc_addr uint32_t;
this matches the VMStateDescription, and also conforms to how
hardware works: the registers don't magically become larger
if the device is attached to a CPU with a larger physical
address size. It also fixes a compile failure if the
target_phys_addr_t type is changed to 64 bits.
