qemu-doc: Update to use the new way of attaching USB devices

Browse source 
The preferred way of adding USB devices is via "-device" and
"device_add" nowadays, so let's start to get rid of "-usbdevice"
and "usb_add" in the documentation. While we're at it, also
add the new USB devices there which have been added to QEMU
during the last years, and get rid of the old "vendorid" and
"productid" parameters of "-usbdevice serial" which have been
removed in QEMU version 0.14.0 already.

This lets you control I/O ports and IRQs.
* -usbdevice serial:vendorid=VID,productid=PRID becomes
-device usb-serial,vendorid=VID,productid=PRID
* -usbdevice serial::chardev becomes -device usb-serial,chardev=dev.
* -usbdevice braille doesn't support LEGACY-CHARDEV syntax. It always
uses "braille". With -device, this useful default is gone, so you
have to use something like
-device usb-braille,chardev=braille,vendorid=VID,productid=PRID
-chardev braille,id=braille
-device usb-braille,chardev=braille -chardev braille,id=braille
* -virtioconsole becomes
