[PATCH 5/9] ARM: dts: exynos: correct PMIC interrupt trigger level on Arndale Octa
From: Krzysztof Kozlowski <krzk@kernel.org>

The Samsung PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU. The falling edge
interrupt will mostly work but it's not correct.
