media: imx: imx7_mipi_csis: Fix logging of only error event counters

[ Upstream commit d2fcc9c2de1191ea80366e3658711753738dd10a ]

The mipi_csis_events array ends with 6 non-error events, not 4. Update
mipi_csis_log_counters() accordingly. While at it, log event counters in
forward order, as there's no reason to log them backward.
