media: uvcvideo: eUSB2 double isochronous bandwidth support

Use usb_endpoint_max_esit_payload() from the USB framework to find the
maximum bytes per interval for the endpoint. Consequently this adds eUSB2
isochronous mode and SuperSpeedPlus Isochronous Endpoint Companion support
where larger payloads within a service interval are possible.
