USB: remove bogus USB_PORT_FEAT_*_SPEED symbols
This patch (as1348) removes the bogus USB_PORT_FEAT_{HIGHSPEED,SUPERSPEED} symbols from ch11.h. No such features are defined by the USB spec. (There is a PORT_LOWSPEED feature, but the spec doesn't mention it except to say that host software should never use it.) The speed indicators are port statuses, not port features. As a temporary workaround for the xhci-hcd driver, a fictional USB_PORT_STAT_SUPER_SPEED symbol is added.
