usb: dwc3: core: avoid Overflow events

Browse source

commit e71d363d9c upstream.

Now that we're handling so many transfers at a time
and for some dwc3 revisions LPM events *must* be
enabled, we can fall into a situation where too many
events fire and we start receiving Overflow events.

Let's do what XHCI does and allocate a full page for
the Event Ring, this will avoid any future issues.
