thermal: rcar_gen3_thermal: disable interrupt in .remove
Currently IRQ remains enabled after .remove, later if device is probed, IRQ is requested before .thermal_init, this may cause IRQ function be called before device is initialized. this patch disables interrupt in .remove, to ensure irq function only be called after device is fully initialized.
