[media] vb2: Add support for non monotonic timestamps
Not all drivers use monotonic timestamps. This patch adds a way to set the timestamp type per every queue. In addition, set proper timestamp type in drivers that I am sure that use either MONOTONIC or COPY timestamps. Other drivers will correctly report UNKNOWN timestamp type instead of assuming that all drivers use monotonic timestamps.
