Krzysztof Kozlowski d788a900f3 ARM: dts: exynos: correct PMIC interrupt trigger level on Odroid X/U3 family
[ Upstream commit 6503c568e97a52f8b7a3109718db438e52e59485 ]

The Maxim PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU.  Without specifying the
interrupt type in Devicetree, kernel might apply some fixed
configuration, not necessarily working for this hardware.

Additionally, the interrupt line is shared so using level sensitive
interrupt is here especially important to avoid races.
