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.
This makes usb.h and usbdevice.h incompatible. Fortunately the only place that tries to include both are the old MUSB code and it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute on musb_regs structure but this attribute seems to be unneeded (old MUSB code doesn't support any DMA at all).

--- Changes in v5: - rebase, compile fix (use usb_config_descriptor)
Changes in v4: - fix indent
Changes in v3: - fix old MUSB code compilation
