[PATCH 2/4] i2c: riic: Use the "dev_name:irq_name" format for the interrupt name

[Claudiu Beznea <claudiu.beznea@kernel.org>]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Use the "dev_name:irq_name" format for the interrupt names. This makes it
easier to identify interrupts in systems where multiple devices may request
interrupts with the same name.
