Linux usb/ch9.h seems to have all the same information (and more) as usbdescriptors.h so use the former instead of the later one.
As a consequense of this change USB_SPEED_* values don't correspond directly to EHCI speed encoding anymore, I've added necessary recoding in EHCI driver. Also there is no point to put speed into pipe anymore so it's removed and a bunch of host drivers fixed to look at usb_device->speed instead.
Old usbdescriptors.h included is not removed as it seems to be used by old USB device code.
