media: rzg2l-cru: Remove debug printouts from irq

Using dev_dbg() in irq handlers to debug per-frame events is marginally
useful and possibly not the best idea, as using printk-based helpers
introduce latencies that impact the drivers operations.

If any tracing/debugging has to be performed around frame events
in interrupt handlers, the tracing subsystem offers better alternatives.

Drop dev_dgb() calls from the CRU interrupt handlers.
