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).
