media: platform: renesas: rzg2l-cru: Add missing documentation for image_conv_irq

Add missing documentation for image_conv_irq element in
struct rzg2l_cru_dev.

Documentation needed to avoid build warning with W=1 builds. It doesn't
really add any non obvious information but good to have it anyway.
