#n is a C preprocessor feature that expand the 'n' argument to a "n"
string, so:

TYPE_ICH9_USB_UHCI(1) = "ich9-usb-uhci" #1
                      = "ich9-usb-uhci" "1"
                      = "ich9-usb-uhci1"

I'm pretty sure we use that elsewhere. If not, I can add a definition
for each 1 ... 6 typenames.
