It has been deprecated, printing a warning message, for almost 4 years
now, and had your ack originally :-)

usb: Deprecate the legacy -usbdevice option
The '-usbdevice' option is considered as deprecated nowadays and
we might want to remove these options in a future version of QEMU.
So mark this options as deprecated in the documenation and print out
a warning if it is used to tell the user what to use instead.
While we're at it, improve also some other minor USB-related spots
in qemu-options.hx that were not up to date anymore.

There's some tradeoff to be had. The 3rd party docs will be unlikely
to be updated to the new syntax as long as the old syntax still works.
So we get ourselves into a chicken & egg scenario.
Overall the -usbdevice doesn't add significant syntax sugar benefits
over -device, as compared benefits of other syntax sugar args we
have.

It seems this is incomplete though, I missed qemu-options.hx,
docs/qdev-device-use.txt and hw/usb/bus.c updates to remove
associated cruft.
