[PATCH 3/8 v3] thermal: rcar: check irq possibility in rcar_thermal_irq_xxx()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

Current rcar thermal driver sometimes checks irq possibility when it
calls rcar_thermal_irq_enable/disable(), but sometimes not.
This patch checks it inside rcar_thermal_irq_enable/disable().
