MdeModulePkg/Xhci: Fill the 'interval' field for ISO endpoint context

Browse Source 
https://bugzilla.tianocore.org/show_bug.cgi?id=510

The commit fills the 'Interval' field of the Endpoint Context data for
isochronous endpoints. It will resolve the error when a Configure
Endpoint Command is sent to an isochronous endpoint.
