EHCI: fix off-by-one error in ehci_submit_root()
USB devices on the 2nd port are not detected and I get the following message:
The request port(1) is not configured
That's with default CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS value of 2. 'req->index'
is 1-based, so the comparison in ehci_submit_root() can't be correct.
