additional sanity checks to allow using the second port on devices
where it is available.

Subject: [PATCH] USB: EHCI: allow limiting ports for ehci-platform
In the same way as the ohci platform driver allows limiting ports,
enable the same for ehci. This prevents a mismatch in the available
ports between ehci/ohci on USB 2.0 controllers.
This is needed if the USB host controller always reports the maximum
number of ports regardless of the number of available ports (because
one might be set to be usb device).
