usb: dwc2: host: Rename some fields in struct dwc2_qh
This no-op change just does some renames to simplify a future patch. 1. The "interval" field is renamed to "host_interval" to make it more obvious that this interval may be 8 times the interval that the device sees (if we're doing split transactions). A future patch will also add the "device_interval" field. 2. The "usecs" field is renamed to "host_us" again to make it more obvious that this is the time for the transaction as seen by the host. For split transactions the device may see a much longer transaction time. A future patch will also add "device_us". 3. The "sched_frame" field is renamed to "next_active_frame". The name "sched_frame" kept confusing me because it felt like something more permament (the QH's reservation or something). The name "next_active_frame" makes it more obvious that this field is constantly changing.
