usb: reword -usb command-line option and mention xHCI 



The -usb section of the man page is not very clear on what exactly -usb
does and fails to mention xHCI as a modern alternative (-device
nec-usb-xhci).

Enable the USB driver (if it is not used by default yet).

Enable USB emulation on machine types with an on-board USB host controller (if

not enabled by default).  Note that on-board USB host controllers may not

support USB 3.0.  In this case @option{-device qemu-xhci} can be used instead

on machines with PCI.
