[PATCH 5/4] usb: Remove "-usbdevice ccid"

[Thomas Huth <thuth@redhat.com>]

"-usbdevice ccid" was not documented and -usbdevice itself was marked
as deprecated before QEMU v6.0. And searching for "-usbdevice ccid"
in the internet does not show any useful results, so likely nobody
was using the ccid device via the -usbdevice option. Remove it now.
