[PATCH] remove CONFIG_USB_LONG_TIMEOUT
Basically, no point in having short and long timeout options
where both are _shorter_ than the timeout from the USB spec.

-config USB_LONG_TIMEOUT
- bool "Long timeout for slow-responding devices (some MGE Ellipse UPSes)"
- depends on USB
- help
- This option makes the standard time out a bit longer. Basically,
- some devices are just slow to respond, so this makes usb more
- patient. There should be no harm in selecting this, but it is
- needed for some MGE Ellipse UPSes.

- If you have an MGE Ellipse UPS, or you see timeouts in HID
- transactions, say Y; otherwise say N.
