usb: cdns3: rename hibernated argument of role->resume() to lost_power

The cdns_role_driver->resume() callback takes a second boolean argument
named `hibernated` in its implementations. This is mistaken; the only
potential caller is:

int cdns_resume(struct cdns *cdns)
{
	/* ... */

	if (cdns->roles[cdns->role]->resume)
		cdns->roles[cdns->role]->resume(cdns, cdns_power_is_lost(cdns));

	return 0;
}

The argument can be true in cases outside of return from hibernation.
Reflect the true meaning by renaming both arguments to `lost_power`.
