All interrupts from SoC internal modules are level triggered, so fix
incorrect trigger type for I2S1 device on Exynos5433 SoCs.

This fixes following kernel warning:

WARNING: CPU: 2 PID: 1 at drivers/irqchip/irq-gic.c:1016 gic_irq_domain_translate+0xb0/0xb8

Hi Arnd and Olof,

That's one fix for current release cycle (issue introduced in merge window).

Best regards,
Krzysztof
