usb: Un-deprecate -usbdevice (except for -usbdevice audio which gets removed)
When trying to remove the -usbdevice option, there were complaints that "-usbdevice braille" is still a very useful shortcut for some people. Thus we never remove this option. Since it's not such a big burden to keep it around, and it's also convenient in the sense that you don't have to worry to enable a host controller explicitly with this option, we should remove it from he deprecation list again. However, there is one exception: "-usbdevice audio" should go away, since audio devices without "audiodev=..." parameter are also on the deprecation list and you cannot use "-usbdevice audio" with "audiodev".

The ``-usbdevice DEV`` argument is now a synonym for setting
|
|
||||||
the ``-device usb-DEV`` argument instead. The deprecated syntax
|
|
||||||
would automatically enable USB support on the machine type.
|
|
||||||
If using the new syntax, USB support must be explicitly
|
|
||||||
enabled via the ``-machine usb=on`` argument.

This option lacked the possibility to specify an audio backend device.

Use ``-device usb-audio`` now instead (and specify a corresponding USB
